    Abstract

    The photophysical properties of 5,10,15-Tris(pentafluorophenyl) corrole (F15TPC) and its porphyrin analogue 5,10,15,20-Tetra(pentafluorophenyl)porphyrin (F20TPP) were investigated through the steady-state and the time-resolved transient spectroscopy. The results show a wide B band absorption peak for F15TPC, and a sharp peak for F20TPP. The Q band of F15TPC has two absorption peaks, while the F20TPP has four. The luminescence quantum yield and fluorescence life time for F15TPC and F20TPP are 0.15, 4.8 ns and 0.05, 11.1 ns, respectively. The F15TPC is characterized by high luminescence quantum yield and short fluorescence life time compared with F20TPP. The calculation results show that the F15TPC has large emission rate constant and nonemission rate constant. These may be ascribed to the changed electronic structure of the F15TPC chromophore for the lack of a fluorophenyl and its unsymmetrical and non-planar spatial structure.
