A convenient and effective synthesis of various novel beta-perfluoroalkylated subporphyrins has been developed. beta-Trifluoromethylated subporphyrins were efficiently synthesized by the reaction of brominated subporphyrins with FSO2CF2CO2Me/CuI [with or without Pd(dba)(2)]. Potentially valuable beta-perfluoroalkylated, beta-monotetrafluorobenzo, and beta-monotrifluorobenzo subporphyrins were successfully obtained by a modified sulfinatodehalogenation reaction. Photophysical and electrochemical studies on several typical perfluoroalkylated subporphyrins demonstrated that beta-hexakis-trifluoromethylated subporphyrins show an obviously red-shifted UV/Vis absorption band that arises from macrocycle nonplanar distortion induced by trifluoromethyl groups, but this distortion is not so severe as that of the corresponding beta-octakis(trifluoromethyl)meso-tetraphenylporphyrin. This was supported by their redox potential data. In addition, beta-monotrifluorobenzo subporphyrin exhibits a special fluorescence spectrum of vibronic structure.
