中文摘要：

在 acetonitrile 的 fluorenone (FL ) 的最低激动的三位字节状态的性质，乙醇醋酸盐，甲苯，环己烷用解决时间的激光闪光光分解作用被调查了。相应阳离子激进分子和阴离子激进分子的外观建议电子转移反应发生在 3FL* 和胺之间。试验性的结果与减少溶剂极性一起在熄灭的率常数显示出减少。熄灭 FL 的率常数的变化与三 N 使三位字节激动， N-dimethylaniline 衍生物用 Hammett 常数被解释。

英文摘要：

The property of the lowest excited triplet state of fluorenone （FL） in acetonitrile, ethyl acetate, toluene, cyclohexane has been investigated using time-resolved laser flash photolysis. The appearances of the corresponding cation radicals and anion radicals suggest that the electron transfer reaction occurs between 3FL＊ and amines. Experimental results show a decrease in the quenching rate constants along with reducing solvent polarity. The change of quenching rate constants of the FL excited triplet with the three N,N-dimethylaniline derivatives are explained using the Hammett constant.
