| 摘 要： | 通过对卟啉酞菁二元分子TTPP-O-Pc和TTPP-O(CH_2)_5-O-Pc的发射光谱和激发光谱的系统研究,证实了(tetratolylphenyl porphyrin)TTPP到Pc的能量转移,区分了后一种材料中发射光谱的两组谱带的来源.利用非简并四波混频(NDFWM)方法研究了二元分子激发态弛豫过程,获得了这两种材料的激发态弛豫时间分别为3.6ps和4ps,以及电荷弛豫时间分别为18.5ps和82ps.

| Abstract: | The confirmation of energy transfer from TTPP to Pc in binary molecules of TTPP-O-Pc and TTPP-O-(CH2)5-O-PC has been made by studying the luminescence and excitation spectra, and the two emission bands in the latter were distinguished. The nondegenerate four-wave mixing (NDFWM) was employed to investigate the relaxation processes of excited states (τ1) and charge transfer (τ2). The relaxation times of τ1 and τ2 were, for the first time, obtained to be 4.5 ps and 18.5 ps for TTPP-O-Pc, and 4.2 ps and 82 ps for TTPP-O-(CH2)5-O-Pc. |
