    Carbon nanotubes (CNTs) are promising materials for gas sensing because of their large specific area and high sensitivity to charge differentiation. In CNT-based field-effect transistors (FETs) for gas sensing, both CNT potential modulation in the channels and Schottky barrier height modulation at the CNT/metal electrode contact influence the current properties. However, researchers have not used Schottky barrier height modulation for gas detection. To investigate and compare the effects of Schottky barrier height modulation and CNT channel potential modulation on NO<sub>2</sub> gas exposure, we fabricated ambipolar CNT FETs by the dielectrophoretic assembly. We exposed CNT FET gas sensors to N<sub>2</sub> gas containing 100-ppb NO<sub>2</sub> and observed two different responses in the electric properties: a steady current shift in the positive direction in the hole-conduction region because of the channel potential modulation, and an abrupt decrease in transconductance in the electron-conduction region because of the Schottky barrier modulation. The CNT channels and CNT/metal contact both contributed to the sensor response, and the modulation rate of the Schottky barrier was higher than that of the CNT potential shift in the channel.

    The development of chemical doping methods for carbon nanotubes (CNTs) is essential for various electronic applications. However, typical p-doping methods for CNT thin-film transistors (TFTs), using oxygen and water from the atmosphere, are quite sensitive to changes in the surrounding environment, and thus, their poor temperature tolerance is a critical problem during device fabrication. As a p-dopant for CNT–TFTs, we used 1,4,5,8,9,11-hexaazatriphenylenehexacarbonitrile (HATCN), which is a strong electron acceptor aromatic compound. The HATCN-doped CNT–TFTs exhibited p-type characteristics after exposure to a high-temperature environment of 200 °C, and prolonged heating did not degrade the p-doping performance of HATCN. In addition, stable p-type characteristics even under ambient conditions were obtained by encapsulating the surface of the device with a Parylene–Al<sub>2</sub>O<sub>3</sub> bilayer.

    This study describes the concise exfoliation of multilayer Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> MXene containing residual aluminum atoms. Treatment with tetramethylammonium base in a co-solvent of tetrahydrofuran and H<sub>2</sub>O produced single-layer Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub>, which was confirmed via atomic force microscopy observations, with an electrical conductivity 100+ times that of Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> prepared under previously reported conditions. The scanning electron microscopy and X-ray diffraction measurements showed that the exfoliated single-layer Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> MXenes were reconstructed to assembled large-domain layered films, enabling excellent macroscale electric conductivity. X-ray photoelectron spectroscopy confirmed the complete removal of residual Al atoms and the replacement of surface fluorine atoms with hydroxy groups. Using the exfoliated dispersion, a flexible transparent conductive film was formed and demonstrated in an electrical application.

    The gel column chromatographic separation technique is one of the most rapid and reliable methods to prepare high-purity semiconducting single-wall carbon nanotubes (SWCNTs). However, the use of the expensive dextran-based gels limits the utility and scalability of this technique. Herein, we report the cross-linking gelation of a cost-efficient polysaccharide isomaltodextrin (IMD) for the high-purity separation of s-SWCNTs by column chromatography. The cross-linking reaction with epichlorohydrin under precisely controlled basic conditions gave the sub-micrometer porous IMD gels, which was important for achieving gel chromatographic SWCNT separation. Furthermore, the thin-film transistors prepared from the separated s-SWCNTs exhibited excellent on/off ratios.

    © Copyright 2018 American Chemical Society. DySc2N@C80 is an endohedral metallofullerene showing single-molecule magnet (SMM) behavior. In this work, we encapsulated DySc2N@C80-SMMs into the internal one-dimensional nanospace of single-walled carbon nanotubes (SWCNTs). Using transmission electron microscopy, &quot;peapod&quot; structures were clearly observed. From magnetic field dependent measurements, DySc2N@C80 showed stepwise hysteresis characteristic of SMMs even inside the SWCNTs, and the coercivity increased from 0.5 to 4 kOe. In addition, it showed slow relaxation of the magnetization without an applied external magnetic field. This system is the first example where SMMs have been encapsulated in SWCNTs, and this system could be used in future molecular-spintronics devices.

    Endohedral metallofullerenes have been extensively studied since the first experimental observation of La@C-60 in a laser-vaporized supersonic beam in 1985. However, most of these studies have focused on metallofullerenes larger than C-60 such as (metal)@C-82, and there are no reported purified C-60-based monomeric metallofullerenes, except for [Li@C-60] +(SbCl6)-salt. Pure (metal)@C-60 compounds have not been obtained because of their extremely high chemical reactivity. One route to their stabilization is through chemical functionalization. Here we report the isolation, structural determination and electromagnetic properties of functionalized crystalline C-60-based metallofullerenes Gd@C-60(CF3)(5) and La@C-60(CF3)(5). Synchrotron X-ray single-crystal diffraction reveals that La and Gd atoms are indeed encapsulated in the I-h-C-60 fullerene. The HOMO-LUMO gaps of Gd@C-60 and La@C-60 are significantly widened by an order of magnitude with addition of CF3 groups. Magnetic measurements show the presence of a weak antiferromagnetic coupling in Gd@C-60(CF3)(3) crystals at low temperatures.

    We investigated the energetics and electronic structures of B3N3-doped graphene using the density functional theory with the generalized gradient approximation. Our calculations showed that all of the B3N3-doped graphene structures were semiconductors, irrespective of the periodicity of the B3N3 embedded into the graphene network, in contrast to graphene nanomeshes which are either semiconductors or metals depending on the mesh arrangement. The B3N3-doped graphene has small effective masses for both electron and hole. The band gap in the B3N3-doped graphene networks was inversely proportional to the B3N3 spacing. The total energy of the B3N3-doped graphene was also inversely proportional to the B3N3 spacing. The band gap and total energy further depended on whether the graphene region possessed a Clar structure or not. In particular, the sheets with a Clar structure had a wider band gap and a slightly lower total energy than those without a Clar structure.

    In this work, we tried to develop a stable CNT-doping method by the encapsulation of halogenation reagents. Although we confirmed that bromine atoms were encapsulated into CNTs using bromination reagents and p-type doping was achieved in Raman spectra, the encapsulation of the dopant was not efficient enough to change the transistor characteristics. However, in the course of the study, it was confirmed that some organic oxidants acted as p-dopants with high-temperature conditions and long-term stability. We also established separation techniques for separating semiconducting CNTs and a novel fabrication method for forming CNT thin films, which were necessary to fabricate thin-film transistor for the evaluation of doping efficiency.

    <BR>
    単層カーボンナノチューブ (SWCNT)内部で原子層物質で最も代表的なグラフェン・ナノリボンの合成実験を開始した。グラフェン・ナノリボンの合成はジブロモ・ビアントラセンを用いた。これは、SWCNTの内部直径とジブロモ・ビアントラセンの幅は丁度フィットするためである。SWCNTへの内包は昇華法を用いた。透過型電子顕微鏡(TEM)観察では、SWCNT内部に内包されたジブロモ・ビアントラセンを確認することが出来た。今後は、これを高温熱処理をして実際にSWCNT内部でグラフェン・ナノリボンが生成されるかをTEM観察する。

    Utilizing inner space of carbon nanotubes, new synthetic methods for one-dimensional nanomaterials were accomplished. Instead of the thermal coalescence of encapsulated molecules, novel one-dimensional nanomaterials were synthesized efficiently through carbon-carbon bond or hydrogen bond formation under mid conditions. We demonstrate the synthesis of one-dimensional diamondoid polymers or long polythiophenes. Especially, polythiophenes, encapsulated in carbon nanotubes, showed s-trans co-planar conformation even at solid state. In addition, selective p-doing to metallic carbon nanotubes were observed after the encapsulation of polythiophenes.

    We have tackled the solubilization and the isolation of metallofullerene, which is a one of the promising nanocarbon materials, by the encapsulation with novel macrocyclic compounds. We have found that the pi-conjugated macrocycles are effective for the size-selective encapsulation of fullerenes. Using this technology, the size-selective extraction of metallofullerene have been achieved. We have also designed new macrocycles for the encapsulation of fullerenes and revealed the stabilization energies, the collaboration work with theoretical scientists.

    カーボンナノチューブは稀少金属などを一切含まない炭素原子のみから構成され、高い機械的強度・電気伝導性・超電導性など様々な機能を持つため非常に注目されている次世代マテリアルである。1991年に飯島らによって発見されて以来世界中で研究されているが、直径・長さ・構造を制御した純粋なカーボンナノチューブ合成は未だ達成されておらず、学術的に大きなインパクトを与えるだけでなく産業界において強く望まれている技術である。
    有機化学的なビルドアップによる、分子式として表せる純正カーボンナノチューブの完全化学合成を目標として研究を行った。我々はすでにアームチェア型カーボンナノチューブの最短骨格であるシクロパラフェニレンの直径選択的な自在合成法の開発に成功している。また、シクロパラフェニレンこの側面構造と直径という「情報」が埋め込まれていると考え、テンプレートとすることでそれぞれに対応するカーボンナノチューブを合成できると予想した。そこで様々な合成法と詳細な条件を検討した結果、シクロパラフェニレンに対して減圧条件下でエタノールと反応させることによってカーボンナノチューブの生成が確認された。透過型電子顕微鏡観察やラマン分光法などによって合成したカーボンナノチューブを評価したところ、用いるシクロパラフェニレンのサイズに近い直径分布が観測されており、この事実もシクロパラフェニレンがテンプレートとして働いていることを示唆している。また、高温下でのシクロパラフェニレンの高温下での挙動の調査することで、新たなカーボンナノチューブの生成機構についての提唱も行なっている。いまだ収量など改善の余地が残るものの、これらの結果は選択的なカーボンナノチューブの自在合成法に向けた重要な一歩といえる。
