We will present the synthesis of POR-PDI dyad bridged with a triazine linker and illustrate the energy diagram of POR-PDI dyad to show the potential photoinduced electron transfer process.We will further present the results of absorption and fluorescence determination. It's indicated that intramolecular photoinduced energy transfer takes place in dyad from excited PDI moiety to the POR moiety, whilst efficient intramolecular photoinduced electron transfer occurs from excited POR moiety to the PDI moiety. The kinetic analysis via transient fluorescence spectra indicated that there occur fast photoinduced electron transfer and low charge recombination.Finally, a comparison of kinetics of electron transfer among different POR-PDI systems other donor-acceptor dyads with a triazine linker will be made.
