| 摘 要： | 设计、合成了以杯[4]芳烃为平台,以氨基吡啶基团为双识别位点的新型化学传感器,并用红外光谱、质谱、核磁共振和元素分析方法对其进行了表征。紫外和荧光光谱研究结果表明,该受体分子在二氯甲烷溶液中能选择性识别脂肪二酸,络合常数可达103~104L/mol,络合能力大小顺序为:丙二酸>草酸>丁二酸>戊二酸>已二酸。 |
| 关 键 词： | 杯[4]芳烃 化学传感器 分子识别 脂肪二酸 |

| Abstract: | A new chemosensor was prepared from a calix[4]arene platform and two 2-aminopyridine recognition sites,and its chemical structure was identified by FT-IR,MS-FAB,~1H-NMR,~13C-NMR and elemental analyses.UV-Vis and fluorescent titration experiments demonstrated that the molecular receptor was able to bind dicarboxylic acids in CH_2Cl_2 with apparent binding constants ranging from 10~3 to 10~4 L/mol,and its binding ability for dicarboxylic acids in the following order:malonic>oxalic>succinic>glutaric>adlpic. |
| Keywords: | calix[4]arene chemosensor molecular recognition dicarboxylic acid |
