| 摘 要： | 我们已报道咔唑和对苯二甲酸二甲酯(DMTP)不能生成激基复合物[1],DMTP仅能猝灭咔唑的荧光。这一现象可用激发态的咔唑与猝灭剂之间形成氢键[2]加以解释,也可以用激发态的咔唑中-NH基与猝灭剂的吸电性较强的侧基之间的相互作用解释[3]。因此我们开展了下面的研究,实验结果表明,本文采用的体系,猝灭剂中侧基的吸电性对荧光猝灭有很大的影响.

| Abstract: | In this paper, fluorescence quenching of carbazole was studied. For homologue p-X-C6H4COOH, quenching constant kq depends on the Hammett constant of X-C6H4COOH. Plotting Ig kq against Hammett constant of X-C6H4COOH, a straight line is obtained. |
