Research Abstract

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.
