Abstract:We report herein the electron transfer process of a novel supramolecular dyads composed of zinc tetraphenylporphyrin (ZnTPP) and zinc 5,15‐dinonyl‐10,20‐diphenylporphyrin (ZnDPP), as electron donors, and ethyl(4‐pyridyl) coumarin‐3‐carboxylate (EPCC), as an electron acceptor, through metal‐ligand coordination bond in dichloromethane. The optical absorption studies revealed the formation of the moderate stable supramolecular donor‐acceptor dyads. The fluorescence measurements showed a significant fluorescence q… Show more
