摘要: 本工作对两种不同的2-芳基苯并 唑化合物溶液荧光被四氯化碳所猝灭的机理进行了详细研究,通过多种途径研究表明该猝灭过程具有光诱导电子转移性质,工作还利用此电子转移所形成的活泼自由基来引发烯类单体的聚合,得到了有一定聚合度的聚甲基丙烯酸甲酯。

Abstract: In this work, the mechanism of fluorescence quenching of 2-aryl benzoxazole in different solvents by carbon tetrachloride has been studied.It is found that there is an unequivocal electron transfer character observed in the quenching process by several ways. At the same time,the active radicals formed from the process of electron transfer was utilized to initiate the polymerization of MMA monomer, and PMMA with certain degree of polymerization was obtained.

Key words: 2-aryl benzoxazole, fluorescence quenching, photoinduced electron transfer
