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,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。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 We have reported that carbazole and dimethyl terephthalate (DMTP) can not generate exciplex, and DMTP can only quench the fluorescence of carbazole. This phenomenon can be explained by the formation of hydrogen bonds between excited carbazoles and quenchers, or by the interaction between the -NH groups in the excited carbazole and the more electron-withdrawing side groups of the quencher Explain the role. Therefore, we carried out the following research, the experimental results show that the system used in this article, quenching side of the base of the power of the Ying
