摘要

通过采用稳态和飞秒荧光上转换的激光光谱技术，测量了三种新型光敏剂镓Corrole：F10-Ga、P-OH-Ga及P-P-Ga分别在非极性溶剂甲苯和极性溶剂乙醇中的吸收和发光过程。结果表明，苯环上的单羟基与吩噻嗪取代对镓Corrole的吸收和发光性能影响不明显。而三种镓Corrole在乙醇中的B带吸收峰都明显蓝移、荧光峰则明显红移、荧光量子产率减小，而且激发态弛豫过程S

→S

明显比在甲苯中慢。

Abstract

The steadystate spectroscopy and the femtosceond fluorescence upconversion in three kinds of Ga Corroles in toluene and ethanol solvent have been studied. The results show that the effect of the hydroxyl and PTZ substitution on the properties of those Corroles is not significant. In contrast

the blue shifts in absorption spectra

the red shifts in emission spectra and the reduction in fluorescence quantum yield observed when ethanol replaces toluene as a solvent. Moreover

the ultrafast dynamics S

→S

of those Corroles varied significantly in different solvents. Evidently

solvent has a significant effect on those Corroles-energy level structure and optical properties.
