Abstract
A platinum octaethylporphyrin (PtOEP)-diphenylanthracene (DPA) dyad with an ethynylene linker was synthesized. PtOEP and DPA were used as a triplet sensitizer/energy donor and energy acceptor, respectively. UV–vis spectra suggested significant electronic coupling between PtOEP and the ethynylene linker in the ground state. Compared with the non-substituted PtOEP, emission from PtOEP in the dyad was almost completely quenched probably due to triplet excitation energy transfer from PtOEP to DPA.
