| Abstract: | A novel method for the fabrication of a charge‐transfer complex crystal was developed. Photoirradiation of a solution of TPP[Co(tbp)(CN)2] and TPP[Co(Pc)(CN)2] (tbp=tetrabenzoporphyrin, Pc=phthalocyanine, TPP=tetraphenylphosphonium) gave a molecular conducting crystal of a charge‐transfer complex TPP[Co(tbp)(CN)2]2, which was produced by the process in which the photoexcited electron in tbp was transferred from the LUMO of tbp to that of Pc. |
