| 摘 要： | 以杯[4]芳烃为平台、氨基吡啶基团为识别位点、萘环为荧光基团,合成了一类新型荧光化学传感器.采用红外光谱、质谱、核磁共振和元素分析方法对产物进行了表征,并对产物的性能及荧光分子识别有机酸的机理进行了研究.结果表明,所合成的荧光分子在乙腈溶液中能选择性识别芳香族有机酸,表现出荧光淬灭现象,其与有机酸络合能力的大小依次为:对氰基苯甲酸>对氯苯甲酸>对甲氧基苯甲酸>苯甲酸.

| Abstract: | A novel calix[4]arene-based fluorescent chemosensor bearing 2-aminopyridine moiety and naphthalenic fluorphore was synthesized,and the chemical structure of the product was identified by FT-IR,MS-FAB,NMR and elemental analyses.Then,the properties and identification mechanism of the synthesized chemosensor were investigated.The results show that the chemosensor exhitits selective fluorescent quenching in the presence of aromatic organic acid in acetonitrile solution,and that the binding ability of the chemosensor with organic acid is in the order of p-cyanic-benzyl acid > p-chloric-benzyl acid > p-methoxyl-benzyl acid > benzyl acid. |
