Outline of Final Research Achievements

To evaluate the intermolecular interaction of small-molecule organic transistor materials, I aim to develop a molecular conductor composed of transistor molecules and to evaluate the transfer integral experimentally in order to consider the contribution of arbitrary electron correlations Although the results were inadequate in terms of target parameters, results in the development of novel molecular conductors were obtained.

Academic Significance and Societal Importance of the Research Achievements

分子性導体の新規開発において一定の成果があった。従来の強相関電子系はBEDT-TTFを主要ドナーとするラジカルカチオン塩であったが、本研究課題では分子性導体の分野では、新しいドナー分子を用いて二次元電子構造をもつ強相関電子系を開発できた。これは学術的に意義があると考えられる。
