| 英文摘要 | The effect of axial ligand 4-N,N-dimethyl aminopyridine (DMAP) on the fluorescence property of the second singlet excited state (S(2)) and first singlet excited state (S(1)) of 5,10,15, 20-tetra(p-methoxyl)phenyl zinc porphyrin has been investigated using steady-state absorption, fluorescence spectroscopy and picosecond time-resolved fluorescence spectroscopy. Hot fluorescence is clearly observed and is then reasonably assigned to the higher vibronic level from S(1) state. A further analysis of fluorescence kinetics results shows that the coordination of DMAP to the zinc ion results in a decrease of hot fluorescence lifetime and an increase of the relative content of hot fluorescence. Similar phenomenon was observed with respects to S(1) fluorescence upon the addition of DMAP in toluene. For a complete understanding of such an effect, a possible mechanism has been put forward and discussed in detail. |
