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.

Molecular orientation of organic monolayers on Si(111)

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 "metallo-DNA" 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).

Analysis of hydrogen-terminated Si(1 1 1) surface by infrared multiple-angle incidence resolution spectroscopy

Hiroyuki Kakuda, Takeshi Hasegawa, Takeshi Hasegawa, Taishi Tanaka, Kentaro Tanaka, Kentaro Tanaka, Mitsuhiko Shionoya

Chemical Physics Letters 415 巻頁： 172-175 2005年10月

掲載種別：研究論文（学術雑誌）

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.
