From the photophysical behaviors of 1, 3, 4-triaryl-2pyrazoline compound (TPP16) at low temperature, it can be considered that the twisted configuration between pyrazoline ring and the non-substituted phenyl group on the position 1 is the fluorescence configuration of conjugated system Ⅰ, and the twisted configuration between pyrazoline ring and P-nitrobenzene group is fluorescence configuration of conjugated system Ⅱ.

研究了1，3，4-三芳基-2-吡唑啉化合物TPP16在低温时的发光情况，发现：在低温77K下，共轭体系Ⅰ(苯基-N1-N2＝C3-苯基)在非极性溶剂中不发荧光，在极性溶剂中有较强荧光发射；而共轭体系Ⅱ(N1-N2＝C3-C4＝对硝基苄叉)在非极性溶剂或极性溶剂中均有荧光发射，表明N1所联取代基与吡唑啉环相扭曲的构象是共轭体系Ⅰ的发光构象，而对硝基苄叉与吡唑啉环相扭曲的构象是共轭体系Ⅱ的发光构象。

A group of pyrylium salts with different substituents has been synthesized in this work. Their fluorescence life time, quantum yield and quenching constant by BVE have also been measured. It was found that a strong interaction was observed between BVE and pyrylium salt which contains an electron-withdrawing group, and contrary, the introduction of electron-repulsive groups to the pyrylium salt will decrease this effect. It indicated that these reactions possess the characteristic of electron transfer.
