摘要: 在合成了几种带不同组成比吖啶基三元共聚物的基础上,对其溶液和薄膜的吸收与荧光发光光谱进行了表征.研究了上述薄膜在含有卤素阴离子溶液中的荧光猝灭问题,发现含有不同吖啶组成比的薄膜对不同卤素离子具有不同的选择性,过多或过少吖啶含量的薄膜均对选择性的识别卤素阴离子不利,只有在某种特定组成条件下方能得到最佳、具有特征识别阴离子能力的薄膜器件.对所得结果进行了详细的讨论.

关键词: 含吖啶基的三元共聚物, 卤素阴离子, 分子识别, 荧光猝灭

Abstract: Based on the synthesis of different terpolymers with acridine group,the absorption and fluorescence spectra of these compounds in solution and membrane were recorded respectively.The fluorescence quenching of membrane of these copolymers by different halides was also studied in this work.It was found that the copolymer with different ratio of composition of acridine contained possesses different selectivity for halides.The unsuitable containing of acridine in copolymers will reduce the ability for the molecular recognition of halides.The good results have been obtained just for the membranes in which certain composition of acridine was contained.A detailed discussion was also included.

Key words: acridine containing terpolymer, halogen anions, molecular recognition, fluorescence quenching
