Novel electron donor molecules composed of tetrathiafulvalene(TTF) and semisquarate ester are prepared. Because of a small amount of charge transfer from the electron-donating TTF unit to the electron-accepting semisquarate unit, these molecules show a solvatochromic effect in solution and electrical conductivity in the solid state in their neutral form. The radical ion salts composed of these donor molecules and magnetic transition-metal anion are also prepared. The antiferromagnetic exchange interaction between localized spins between magnetic anions are mediated by theπ-electron system of the donor molecules.

合成了由四硫富瓦烯（TTF）和半季铵盐组成的新型电子给体分子。由于少量的电荷从给电子TTF单元转移到接受电子的半四价体单元，这些分子在溶液中显示出溶剂化变色效应，并且在固态中以其中性形式显示出导电性。制备了这些给体分子与磁性过渡金属阴离子组成的自由基离子盐。磁性负离子之间的局域自旋之间的反铁磁交换相互作用是由施主分子的π电子系统介导的。
