研究概要

(1)サーモクロミック有機磁性体：基底三重項ビラジカル化合物群が、逐次構造相転移を示し、反磁性から S = 1/2常磁性、S = 1常磁性となることを明らかにした。一つの誘導体で、幅広い温度領域で S = 1/2常磁性を示すものを見いだした。(2)分子包接誘起磁性体：ラジカル置換ホスト分子を合成開発した。金属イオンの有無に従って、開いた構造から閉じた構造に変化し、ホスト分子が基底三重項から基底一重項へスイッチする例を見いだした。(3)有機ラジカル配位磁性材料：4f-3d、4f-2p 系単分子磁石を合成し、へテロスピン間の交換相互作用を決定した。ラジカル希土類錯体自体が類例の少ない物質群である。
