ナノカーボンの任意の炭素をヘテロ元素に置換した含ヘテロナノカーボンは、理論計算により特異な物性を有することが予測されている。しかし、その合成は、小分子を前駆体として用いた化学気相成長法や、ナノカーボンと小分子との熱アニーリングによるものが主であり、ヘテロ原子の導入位置や導入数の制御が困難である。その結果、多くの研究が混合物による表層的な研究に留まっている。このような背景から、本研究室では、含ヘテロナノカーボンの精密合成とそれを通じた学術分野としての深化を目標に据えて合成化学と材料化学の両面から研究を進めている。
Heteronanocarbons, in which specific carbons in nanocarbons (e.g. graphene, fullerene, CNT) are replaced by heteroatoms, are predicted to have unique physical properties and catalytic activities based on theoretical calculations. However, their synthesis is mainly based on chemical vapor deposition using small-molecule precursors or thermal annealing between nanocarbons and the precursors, which makes it difficult to control the position and number of heteroatoms introduced. As a result, most studies have not been beyond superficial research using mixtures. Therefore, we are pursuing research in synthetic and materials chemistry, aiming at the controlled synthesis of the heteronanocarbons and their deepening as an academic discipline.
