研究紹介
 筆者等のグループは「新らしい電子物性を示す分子物質の開発」を目指して研究してきました。具体的には、単一分子性伝導体やアニオンサイトに局在磁気モーメントを導入した磁性有機伝導体の合成、構造解析、および伝導性や磁化率などの基本的な物性測定をおこない、初めての単一種の分子だけで出来た金属結晶や、初めての反強磁性および磁場誘起超伝導体等を報告してきました。本研究計画では、これまでの研究の一層の発展を目指し、以下に示す3つの研究課題について研究を行なう予定です。
(1) 拡張TTF型骨格を持つジチオレン錯体による中性単一分子性金属の開発、
(2) πドナー分子と大きな磁気モーメントを持つ磁性アニオンを組み合わせた磁性有機(超)伝導体の開発とそのキャラクタリゼーション、
(3) ポーラス結晶の分子空間に閉じこめられたゲスト分子の状態変化とそれに伴う誘電転移の可能性。
