Functionalized porphyrin and porphyrin containing trifluoromethyl with ferrocene were synthesized.The UV-Vis absorption bands of porphyrin with an electron withdrawing trifluoromethyl group were blue-shifted and those of porphyrin with an electron donating ferrocenyl group were red-shifted.The porphyrin containing ferrocenyl exhibited strong fluorescence quenching compared with those containing trifluoromethyl.The quenching efficiency of diferrocenyl porphyrin was about 66% with a quantum yield Φf of 0.08.T...
