Synthesis of Phosphole-bridged Porphyrin Dimers
We synthesized phosphole-bridged porphyrin dimers and evaluated their optical and electrochemical properties. The porphyrin dimers exhibited broadened and red-shifted absorption relative to thienylene- and p-phenylene-bridged reference dimers, suggesting effective pi-conjugation between the porphyrins through the phosphole linker. The more positive reduction potentials of phosphole-bridged porphyrin dimers compared to reference dimers are attributed to the electron-accepting ability of the phosphole linker.
