摘要

本文利用吸收光谱、荧光光谱以及时间分辨瞬态吸收光谱研究芘四磺酸四钠盐的光物理特性.研究结果表明

芘四磺酸四钠盐在水溶液中的荧光量子产额高达0.54.在纳秒时间分辨瞬态吸收光谱研究中发现芘四磺酸四钠盐具有很长的三重态寿命(3.5ms)

这有利于将其作为光敏化分子把激发能传给其它受体分子;芘四磺酸四钠盐被光激发后

可能发生双光子吸收过程并产生芘四磺酸四钠盐阳离子

其吸收峰为460nm和505nm.由实验结果

我们给出了其动力学过程的解释.

Abstract

The photophysical properties of PyTS have been studied by steady-state absorption

fluorescence emission and time-resolved transient absorption spectroscopies. PyTS has a high fluorescence quantum yield in water

Φ-=0.54. The PyTS triplet state lifetime we obtained is 3.5 ms from nanosecond transient absorption spectra

its long lifetime is much favourable for excited energy transfer to other molecules as a sensited molecule. It maybe occurs a two photon absorption process which leads to PyTS cation transient absorption at 460 nm and 505 nm when PyTS-was excited. Here we also proposed the dynamic scheme of PyTS from the experimental results.
