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.

本工作合成了一组带不同取代基的氧鎓盐化合物，并对它们的荧光寿命、荧光量子产率以及用丁基乙烯基醚进行猝灭的荧光猝灭常数进行了测定，发现带拉电子基的氧鎓盐化合物和BVE间存在着较强的相互作用，相反，推电子基的引入则减弱了这种影响，表明反应具有电子转移性质。

Results EROD activities in liver of wild crucian from Zhangtan, Jiangjunyan, Fuyang and Wenyan (23.51±4.17, 16.79±7.39, 18.74±5.16, 18.65±8.86 nmol/) were significantly higher than that of Jiekou (7.84±2.42 nmol/g promin), and no difference was observed between the other sites and Jiekou. Three dose groups (0.25, 0.50, 1.00L/dish water sample extracts) were used in Ames test. Reversional mutation rate of TA98 colony exposed to extracts from Zhangtan was 2.21, 3.39, 6.95 without S9, and 2.70, 4.07, 6.23 with S9, respectively. The revesional mutation of TA100 colony was 2.55, 2.81, 5.36 without S9, and 1.73, 2.86, 4.14 with S9, respectively. Reversional mutation rate of TA98 colony exposed to 1.00L/dish extracts from Jiangjunyan with S9 was 2.22, and there was a dose-response relationship in reversional colony count. Ames tests of the other extracts were negative.
