A convenient and effective synthesis of various novel β- perfluoroalkylated subporphyrins has been developed. β-Trifluoromethylated subporphyrins were efficiently synthesized by the reaction of brominated subporphyrins with FSO2CF2CO2Me/CuI [with or without Pd(dba)2]. Potentially valuable β-perfluoroalkylated, β-monotetrafluorobenzo, and β-monotrifluorobenzo subporphyrins were successfully obtained by a modified sulfinatodehalogenation reaction. Photophysical and electrochemical studies on several typical perfluoroalkylated subporphyrins demonstrated that β-hexakistrifluoromethylated 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 β-octakis(trifluoromethyl)-meso- tetraphenylporphyrin. This was supported by their redox potential data. In addition, β-monotrifluorobenzo subporphyrin exhibits a special fluorescence spectrum of vibronic structure.

High reactivity of the boron atom of mesoaryl subporphyrins enables the introduction of a broad range of functional groups to its axial position. Axially fluoro-substituted subporphyrins were easily synthesized upon treatment of axially hydroxyl-substitut
