Research Abstract

Novel heterojunctions have been developed using singel crystals of supramolecular organic conductors. The solvent dependence of crystal morphology, donor/anion ratio and electrical conductivity of the three-component supramolecular organic conductors was observed together with characteristic recyclability of the neutral donor molecule.
