    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.

    © 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.

    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.

    カーボンナノチューブ(CNT)は優れた導電性を有する魅力的な物質であるが、実際に導電性フィルムなどに用いる場合には、ドーピングと呼ばれる正孔の注入を行い導電性を向上が必要である。しかし、臭素など多くのドーピング分子は揮発性や大気不安定性のため、経時変化によりCNTの導電性が減少してしまう問題を抱えている。
    本研究では、臭素前駆体としての有機ブロモ化剤の内包による、効率的なドーピング法の確立を目的とする。内包により外環境から遮断されることで、ドーピングの長期安定性が期待できる。長期間安定なCNTのp型ドーピング法を確立した後には、CNT薄膜を作製し低抵抗な透明導電性フィルムの創出を目指す。
    カーボンナノチューブは優れた導電性を有する魅力的な物質であるが、実際に電子デバイスなどへ応用する場合には、その物性制御が必要不可欠である。本研究では有機化学的なアプローチによるナノカーボン材料の物性変調、特にカーボンナノチューブに着目して研究を行った。まず、ターゲットとなる半導体カーボンナノチューブの精製方法を確立した。これまではカラムや超遠心精製に依存して少量しか得られない精製法がほとんどであったが、水溶性食物繊維であるイソマルトデキストリンを利用した水系2相分離により大量に半導体カーボンナノチューブを得る手法を開発した。本精製方法ではイソマルトデキストリンに含まれる連続する1,6-グルコシド結合の存在が、分離の鍵であることが明らかとなった。さらに、得られた半導体カーボンナノチューブを用いて薄膜トランジスタを作製するにあたり、薄膜の作成方法が極めて重要になる。この点においても熱架橋性アミンポリマーを利用する新手法を開発した。本手法によりポリエチレンナフタレートのようなプラスチックのフレキシブル基板に対してもカーボンナノチューブの成膜が可能になった。実際に作成した薄膜トランジスタはp型特性を示しながらも優れたon/off比とともに高い電流密度で動作することが明らかになった。さらにカーボンナノチューブの内部にグラフェンナノリボンを合成する手法の開発にも成功しており、さらなる研究の発展が期待できる。
    本研究では半導体カーボンナノチューブの精製方法と薄膜トランジスタの作成方法を確立したが、その過程におけるナノカーボン材料の化学的な取り扱いを探索していく上で、当初は想定していない新反応を発見するに至った。具体的には、酸化グラフェンの化学修飾による物性制御とバッテリー応用への展開、そして酸化グラフェンの親水性分離である。今後はカーボンナノチューブに限定せず、様々なナノカーボン材料をターゲットとして研究展開していく予定である。
    本研究の目標をおおよそ達成していることから、今後はカーボンナノチューブに限定せず、様々なナノカーボン材料をターゲットとして研究展開していく予定である。カーボンナノチューブンについてはCMOS型のインバータやリングオシレータといった上位デバイスの作成と評価、また酸化グラフェンデバイスの性能向上にも取り組む予定である。

    本研究課題を始めてから停止まで一ヶ月余りと期日が限られていたため、実質の研究の進展はほとんど無いが、以下にこれまでの進展をまとめる。
    <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。
