摘要: 本工作对带有不同取代基的1,3,5-三芳基-2-吡唑啉类化合物的稳态光物理行为进行了研究,从它们在不同极性溶剂中的吸收光谱和荧光发射光谱以及荧光量子效率的结果表明,这类化合物分子内共轭的及非共轭的光诱导电荷转移的趋向取决于上述两过程间的竞争。

Abstract: In this work, the stationary photophysical behavior of triaryl-2-pyrazoline compounds with different substituted groups was studied. According to the results from the absorption spectra, fluorescence spectra of these compounds in various solvents with different polarity and their fluorescence quantum yields indicated that there are two mechanisms of photoinduced charge transfer process which are intramolecular conjugated and non-conjugated existing in the decay process. And the tendency of transfer reaction depends on the competition of these processes described above.
