Efficacious elimination of intramolecular charge transfer in perylene imide based light-harvesting antenna molecules

Two light-harvesting antenna molecules were obtained by positioning naphthalene monoimide energy donors at the imide position, instead of the bay positions, of perylene imide energy acceptors. Such rational design resulted in a complete suppression of parasitic intramolecular charge transfer without...

Summary:Two light-harvesting antenna molecules were obtained by positioning naphthalene monoimide energy donors at the imide position, instead of the bay positions, of perylene imide energy acceptors. Such rational design resulted in a complete suppression of parasitic intramolecular charge transfer without compromising the desired ultrafast rates of excitation energy transfer. A new design for the perylene dye-based light-harvesting antenna systems is presented, which enables complete suppression of parasitic intramolecular charge-transfer.
