Continuous nanopores within fluid materials could be used for novel chemical events such as the accommodation of guest molecules, unique arrays of the entrapped molecules, and chemical reactions in a dynamic molecular assembly. Columnar liquid crystals composed of a one‐dimensionally stacked assembly of shape‐persistent macrocycles form nanochannels owing to the intrinsic nanospace in the column. However, the existence of substantial nanoporosity has not been confirmed experimentally thus far. In this study, for the first time in the literature, we confirmed the presence of discrete and spatiotemporally continuous voids in a liquid‐crystalline material. In 129Xe NMR spectroscopy of liquid crystalline columnar assembly of imine‐bridged shape‐persistent macrocycles under Xe atmosphere, the NMR signals of the Xe atoms entrapped in the liquid‐crystalline macrocycle depended on the gas pressure and phase‐transition temperatures. These results indicate that the encapsulation of Xe gas molecules within the discrete and oriented nanospaces of nanoporous liquid crystals is different from the homogeneous dissolution of the solute in an ordinary solution.

The design of responsive liquid crystals enables a diversity of technological applications. Especially photochromic liquid crystals gained a lot of interest in recent years due to the excellent spatiotemporal control of their phase transitions. In this work we present calamitic light responsive mesogens based on a library of arylazopyrazole photoswitches. These compounds show liquid‐crystalline behavior as shown by differential scanning calorimetry, grazing incidence X‐ray diffraction and polarized optical microscopy. UV‐vis spectroscopy and NMR analysis confirmed the excellent photophysical properties in solution and thin film. Additionally, polarized optical microscopy studies of the pristine compounds show reversible phase transition upon irradiation with light. Moreover, as a dopant in the commercially available liquid crystal 4‐cyano‐4'‐pentylbiphenyl (5CB), the temperature range was reduced to ambient temperatures while preserving the excellent photophysical properties. Remarkably this co‐assembled system shows reversible liquid‐crystalline to isotropic phase transition upon irradiation with light of different wavelengths. The spatiotemporal control of the phase transition of the liquid crystals offers opportunities in the development of optical devices.

Abstract

Lead phthalocyanine (PbPc) is well known to be used as a good near-infrared (NIR) light absorber for organic solar cells (OSCs) and photodetectors. The monoclinic and triclinic phases have been understood to absorb the visible and NIR regions, respectively, so far. In the present study, we demonstrated from the absorption spectra and theoretical analysis that the visible band considerably originates from not only the monoclinic but also the amorphous and triclinic phases, and revealed the exciton dynamics in the PbPc film from static/time-resolved photoluminescence (PL), which are first reported. By comparing the external quantum efficiency between PbPc- and ZnPc-based OSCs in relation to their structure, morphology, and optical (absorption and PL) characteristics, we unraveled the reasons behind the PbPc film used as a good absorber for NIR-sensitive devices.

A C-4h symmetrically substituted phthalocyanine, 1,8,15,22-tertrakis(2,4-dimethylpent-3-oxy)phthalocyanine (H(2)TdMPPc), was used to synthesize Tb3+-phthalocyanine double-decker complexes ([Tb(TdMPPc)(2)]s). Because H(2)TdMPPc has C-4h symmetry, S,S, R,R, and meso isomers of [Tb(TdMPPc)(2)] were obtained depending on the difference in the direction of the coordination plane of two C-4h-type phthalocyanines with respect to a central Tb3+ ion. We investigated the physical properties of these [Tb(TdMPPc)(2)] isomers, including their single-ion magnetic properties, and found that the spin-reversal energy barrier (U-eff) of the meso isomer was apparently higher than that of the enantiomers. Detailed crystal structural analyses indicated that the meso isomer has a more symmetrical structure than do the enantiomers, thereby suggesting that the higher U-eff of the meso isomer originated from the more highly symmetrical structure.

A novel double-decker porphyrin complex, bis{meso-tetrakis(4-N-alkylpyridiniumyl)porphyrinato}cerium, was prepared. Electrochemical measurements revealed that this complex exhibited reversible redox waves corresponding to a 1e– redox reaction of the cerium center. Treating the complex alternately with an oxidant and a reductant resulted in the reversible redox switching between the oxidized and reduced states in an organic solvent.

A series of π-extended chelating scaffolds incorporating two hydroxypyridone moieties were synthesized. X-ray crystallographic analysis revealed that a bis(hydroxypyridono)toluene ligand possessed a unique π-extended structure and exhibited efficient phase segregation from the aliphatic chains attached at the heterocyclic nitrogen. The bis-bidentate ligand formed a metal-coordination-induced macrocycle with Cu2+ ions. During the complexation, a spectral change in the visible region was induced. Furthermore, the successful development of a liquid crystal of the metallomacrocycle with appropriate side chains was achieved. Examples of liquid-crystalline macrocycles formed via metal-mediated self-assembly are still rare. Among them, the macrocycle described in this paper showed an obvious hexagonal columnar phase reflecting the three-fold symmetric planar structure of the mesogenic metal complex.

© 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim Development of supramolecular methods to further activate a highly reactive intermediate is a fascinating strategy to create novel potent catalysts for activation of inert chemicals. Herein, a supramolecular approach to enhance the oxidizing ability of a high-valent oxo species of a nitrido-bridged iron porphyrinoid dimer that is a known potent molecular catalyst for light alkane oxidation is reported. For this purpose, a nitrido-bridged dinuclear iron complex of porphyrin-phthalocyanine heterodimer 3 5+ , which is connected through a fourfold rotaxane, was prepared. Heterodimer 3 5+ catalyzed ethane oxidation in the presence of H 2 O 2 at a relatively low temperature. The site-selective complexation of 3 5+ with an additional anionic porphyrin (TPPS 4− ) through π–π stacking and electrostatic interactions afforded a stable 1:1 complex. It was demonstrated that the supramolecular post-synthetic modification of 3 5+ enhances its catalytic activity efficiently. Moreover, supramolecular conjugates achieved higher catalytic ethane oxidation activity than nitrido-bridged iron phthalocyanine dimer, which is the most potent iron-oxo-based molecular catalyst for light-alkane oxidation reported so far. Electrochemical measurements proved that the electronic perturbation from TPPS 4− to 3 5+ enhanced the catalytic activity.

In this study, a novel discrete phthalocyanine dimer was prepared in which the relative configuration of each component was tightly and accurately fixed in an H-aggregate form by a rigid U-shaped linker. Electrochemical measurements showed that there were strong intramolecular electronic interactions between the two phthalocyanines.

In this review, we focus on the integrated assemblies of metal complexes and their functional emergence generated by the synergy effects of π-π stacking interaction and metal complexation. Programmable construction of integrated molecular assemblies is the best measure for bringing out the emergent functions which can be evolved from the intermolecular communications of functional molecular components. Combination of π-π stacking interaction and metal complexation allows not only to reinforce the mutual interactions but also to generate the emergent intermolecular communications. This review introduces the recent studies including the synergy effects on electrical, magnetic, catalytic and molecular recognition functions in soft, crystalline and single molecular materials.

9.4 Conclusion: In this study, we demonstrate that biopolymers such as DNA and peptides can be precisely redesigned and reconstructed as templates for homogeneous or even heterogeneous assembly of metal ions in a programmable manner by chemically modiyfing their building blocks. This bottom-up strategy based on biorelated molecules would generate not only a new structuralmotif formetal clusters in the biomolecules but also a metal-triggered information-transfer system. © 2006 Springer-Verlag Berlin Heidelberg.

Besides the biological importance of DNA as storage of genetic information, DNA is a smart molecule to assemble functional units since it is possible to use sequences of nucleobases to encode molecular assembled systems in a predetermined fashion over a wide range in size. This review highlights recent advance in precise control of molecular assembly on DNA templates directed towards functionalized materials.

A versatile preparation method for aromatic zincate compounds through a halogen-zinc exchange reaction using dilithium tetra-tert-butylzincate (tBu4ZnLi2) has been developed. This reagent permits efficient preparation of highly functionalized aromatic zincates, particularly, those with electrophilic functional groups, such as ester, amide, alcohol, and phenol. Halogen-zinc exchange reactions followed by electrophilic trapping (with allyl bromide or benzaldehyde) proved to be a powerful tool for C-C bond formation on functionalized aromatic rings. The functionalized aromatic zincate intermediate was also found to undergo copper- and palladium-catalyzed C-C bond-forming reactions with good yields and high chemoselectivity.

Alkenes form self-assembled monolayers on a hydrogen-terminated Si(111) surface via hydrosilylation of defines. Since the monolayers are attached onto the substrate covalently through direct Si-C bonding, the molecular orientation of the monolayer is strongly influenced by compatibility between the crystal structure of Si(111) surface and the molecular structure of the olefin. In this study, we examined the formation of various monolayers and their molecular orientations on Si(111).

Besides the biological importance of DNA as storage of genetic information, the fundamental and canonical structure of duplex DNA can be regarded as a template for the bio-inspired molecular architectures to develop new functions. DNA has an attractive system to assemble functional building blocks, because automated synthesizers can routinely make oligomers with desired lengths and sequences. Replacement of hydrogen-bonded base pairing of DNA by metal-mediated base pairing could lead to &quot;metallo-DNA&quot; in which metal ions are aligned along the helix axis in a controllable fashion (Chart 1). We report here the de novo designed heterogeneous metal array in artificial metallo-DNA. To heterogeneously array metal ions in double helices, d(5′-GHPHC-3′)2, d(5′-GHHPHHC-3′)2, and d(5′-GHVHC- 3′)2were synthesized, where H is a hydroxypyridone-bearing nucleotide forming a square planar complex with a Cu2+ion, P is a pyridine-bearing nucleotide forming a linear complex with an Ag+or an Hg2+ion, and V is an abasic site. Stepwise photometric titration experiments of Cu2+and subsequent Hg2+to the duplexes and electrospray ionization mass spectroscopy clearly demonstrated the quantitative and site-selective formation of Cu2+-Hg2+-Cu2+, Cu2+-Cu2+-Hg2+-Cu2+-Cu2+and Cu2+- Cu2+arrays in the centers of the duplexes, respectively (Fig. 2).

The infrared multiple-angle incidence resolution spectroscopy (MAIRS) has been employed to analyze the hydrogen-terminated Si(1 1 1) 1 × 1-H surface. The new technique of infrared MAIRS provides two absorption spectra simultaneously on an identical sample, which separately reveal the surface-parallel and surface-normal vibration spectra. It has been exhibited in the present study that the infrared MAIRS technique is powerful to discuss some infrared key bands in terms of molecular orientation concerned with Si-H vibrational modes on the Si(1 1 1) 1 × 1-H surface with the use of the two spectra. © 2005 Elsevier B.V.

DNA has a structural basis for the "bottom-up" fabrication of functionalized molecular building blocks. In particular, the replacement of hydrogen-bonded DNA base pairing for alternative one would lead to a novel tool for re-engineering DNA. Recently, we have synthesized a series of artificial nucleosides bearing metal ligands instead of natural nucleobases and demonstrated that metal complexation between the nucleosides effectively drives base pairing. This review describes our recent approaches to metal-based strategy directed towards self-assembled metal arrays within DNA as well as towards structural control of DNA. This strategy provides a new method for self-assembled metal arrays in a predesigned fashioji, leading possibly to metal-based molecular devices such as molecular magnets and wires.

The structure of DNA is such that the multi-array of functionalized units with desired numbers and sequences within the DNA is possible. In particular, to replace DNA bases, which are biologically important elements for gene expression, by alternative bases would provide powerful tools for programming molecular arrays in a pre-designed manner. This review focuses on recent chemical approaches to

This paper describes design and syntheses of a new class of chelator-type nucleic acid mimics. Four nucleic acid mimics 7, 11, 15, 17 possess a nucleobase and two ethylenediamine moieties for intermolecular metal coordination. We expected that chelator-type nucleic acid mimics formed a strand in the presence of metal ion and then interacted with a single-stranded DNA. Efficient synthetic routes leading to the four nucleic acid analogues have been achieved via the key intermediate compound 5 which was derived from 3,5-dimethylphenol in five steps. Compound 7 was treated with zinc nitrate and Zn complex 8 was isolated as crystals.1H NMR study of Zn complex 8 in D2O showed the single-strand formation. Job plots showed that mixture of (dT)70with Zn complex 8 at 5°C reached a minimum absorbance at a mole ratio of 2:1, and the hypochromic effect showed the π-π stacking interaction between the nucleobases. Thermal denaturation study at 2:1 mole ratio of complexes between (dT)70and Zn complex 8 showed melting point at 27°C. © 2002 Elsevier Science Ltd. All rights reserved.

The metal-chelating β-C-nucleoside having a phenylenediamine moiety as the nucleobase was previously found to form a stable 2:1 complex with a Pd2+ion in aqueous media, where hydrogen bonding is replaced by metal coordination in the base pairing, thereby creating a novel hybridization motif in duplex DNA. In this regard, we have further designed two types of artificial β-C-nucleosides possessing a metal-chelating site (a 2-aminophenol or a catechol) as the nucleobase moiety. These artificial nucleosides are directed toward controlling the net charges of the metal-assisted base pairs. This paper describes convenient syntheses of the artificial nucleosides bearing a 2-aminophenol or a catechol moiety. Each nucleoside was directly synthesized through 2′-deoxy derivative via a Friedel-Crafts coupling reaction as the key step between the aromatic ring and ribose moiety, whereas the nucleoside having a phenylenediamine moiety was prepared in rather longer steps through an RNA type intermediate followed by the removal of 2′-hydroxyl group. © 2001 Elsevier Science B.V.

Novel synthetic approaches for incorporation of metal complexes into nucleic acids and peptides are described. First, novel artificial β-C-nucleosides bearing a chelator nucleobase (2-aminophenol, catechol, or o-phenylenediamine) have been synthesized. These artificial nucleobases were introduced for alternative base pairing through metal coordination instead of the hydrogen bonding in natural DNA.1HNMR and mass spectral studies clearly showed that o-phenylenediamine-type nucleoside forms a stable 2: 1 square-planar complex with a Pd(II) ion, providing an alternative DNA base pairing through metal complexation. Secondly, an efficient strategy for the liquid-phase synthesis of cyclic metallopeptides having a repeating Gly-L-Cys(terpyPt(II)) sequence, cyclo[-Gly-L-Cys(terpyPt(II))-](n)Cl(n) (n = 3, 4), has been developed. These cyclic metallopeptides were obtained by cyclization of the corresponding linear peptides, H2[-Gly-L-Cys(terpyPt(II))-](n)OH-(CF3CO2)(n+1) (n = 3, 4), in moderate yields. The former cyclic hexapeptide was found to act as a positively charged anion receptor. This synthetic approach would provide a powerful tool for arraying metal centers on cyclopeptide frameworks.

It was confirmed by X-ray diffraction patterns and polarized absorption spectra that the dye-intercalated DNA strands were aligned along the dipping direction in the LB film. DNA strands are not aligned in the LB film without intercalating dye molecules. When the DNA-lipid monolayers were deposited by a horizontal lifting method instead of a vertical dipping method, DNA strands were randomly oriented in the film. The orientation of DNAs was decreased when the monolayer packing was decreased by using a low surface pressure or an expanded monolayer. Thus, the rigid, dye-intercalated DNA strands could be oriented during the vertical dipping process.

A novel DNA-lipid complex is prepared by replacing sodium counter cations by cationic amphiphilic lipids (1). The DNA-lipid complex is insoluble in aqueous solutions, but is soluble in most orgamc media such as benzene, ethanol, and chloroform. The DNA-lipid complex was confirmed to form double helical strands even in organic media, and the internal conformation of DNA strands could be reversibly changed from B-form to C-form in the organic solution (CHCl3/EtOH = 4:1) by changing the water content. A self-standing, water-insoluble DNA-lipid (1) film was prepared by casting from the organic solution and could be stretched to produce oriented DNA strands with their axes aligned along the stretching direction. The film can be impregnated with the drug ethidium bromide in the aqueous solution. The linear dichroism characteristics of the drug-DNA film show that the DNA strands are well oriented and the ethidium molecules are intercalated, as they are in normal aqueous solutions.

The formation of Q-state CdS particles in cadmium arachidate (CdAr) Langmuir-Blodgett films has been monitored using the quartz crystal microbalance (QCM) and UV-vis absorption measurements. QCM studies showed that the mass uptake of different thickness CdAr films on exposure to hydrogen sulfide was consistent with that expected for the quantitative conversion of Cd2+ ions in the films to CdS and the corresponding conversion of CdAr to arachidic acid. UV-vis absorbance measurements showed an optical blue shift typical of particles between 2 and 3 nm in diameter. Complimentary electron microscopic studies showed a polydisperse size distribution of CdS particles. The most common particle size observed in the electron micrographs was found to be close to the particle size determined from the optical properties of the semiconductor particles. There was a linear relationship between the mass uptake of a film on H2S exposure and changes in its absorption properties due to Q-state particle formation. The linear relationship was used to calculate the optical extinction coefficient of the Q-state particles in the film. Mass uptake measurements on CdAr films extensively exposed to H2S gas showed that the arachidic acid molecules left after Q-state particle formation could be quantitatively converted to CdAr by immersing the film in a stirred aqueous solution containing cadmium chloride. Subsequent reexposure of the film to H2S increased the mole fraction of CdS in the film. © 1994, American Chemical Society. All rights reserved.

The fabrication of particles in Langmuir-Blodgett films of cadmium icosanoate and nonacosa-10,12-diynoate is followed using a quartz crystal microbalance. The mass changes accompanying the exposure of the film to hydrogen sulfide are consistent with a chemical reaction in the film which also produces the acid form of the surfactant. Film thermal stability is greatly reduced after the particles are formed, a result also consistent with formation of the more volatile acid form. The extent of film removal by heating/outgassing suggests that particles are capped by adsorbed icosano or diynoic acid. It is likely that this capping plays a role in particle growth control.

The growth of Q-state CdS particles during exposure of Langmuir-Blodgett films of cadmium arachidate to hydrogen sulfide has been monitored by surface plasmon resonance (SPR), UV-visible absorption, and quartz crystal microbalance (QCM) measurements. The growth kinetic profile, expressed in terms of increasing refractive index (SPR), absorption or mass increase (QCM), was the same when films were gassed under similar conditions. Microgravimetry showed the quantitative conversion of Cd2+ to CdS in such systems; UV-visible absorption exhibited the blue shift typical of Q-state particles of 2-3-nm diameter. SPR reflectance curves obtained after H2S treatment were initially fitted assuming that either the film thickness or the real component of the relative permittivity (epsilon(r)) was constant during Q-state particle formation. Film thickness changes (assuming epsilon(r) was constant) were similar to those previously reported. Relative permittivity changes, determined assuming the film thickness was constant, indicated that for thinner films (i.e., fewer than about 10 layers) effects such as film breakup during particle;formation and HS exposure to the gold surface of the SPR crystal were important. The change in epsilon(r) for a 20-layer cadmium arachidate film after-extensive gassing was calculated using Maxwell-Garnett theory. Use of this value in the fitting routine indicated that the film thickness change during particle formation was 0.13 nm/layer or 4.9%.

A quartz-crystal microbalance (QCM) was employed as a substrate for a horizontal lifting method of various LB films, in which the QCM plate was touched to monolayers on a subphase and lifted horizontally. The transferred mass of monolayers on the QCM could be measured directly at a nanogram level from a frequency decrease of the QCM plate: two monolayers were deposited each cycle (Y-type, transfer ratio 2). The QCM method gave more precise transfer information than the conventional method using the moving area of the barrier on the trough. It was found by the QCM method that Y-type horizontal lifting methods could be widely applied for most monolayers to form well-layered LB films, compared with the conventional vertical dipping method. © 1992.
