含酰胺基和酯基的新型杯4冠醚的合成及其对金属离子的识别能力

摘要

利用杯[4]芳烃与含酰胺基和酯基的丙二酸酯衍生物的“1+1”分子间缩合合成了一例新型结构的杯[4]-1,3-冠醚；利用核磁共振、红外光谱、质谱及元素分析表征了其结构,并测定了其对金属离子的识别能力.结果表明,合成的新型杯[4]冠醚对金属阳离子和阴离子均有较好的识别能力.%A novel calix[4]-l, 3-crown containing amide and ester groups was synthesized via inter-molecular condensation polymerization of calix[4] arene and malonate derivative containing amide and ester groups. The structure of as-synthesized product was confirmed by nuclear magnetic resonance spectrometry, infrared spectrometry, mass spectrometry and elemental analysis; and its ability to recognize metal ions was evaluated. It has been found that title crown possesses good recognition abilities for metal cations and anions.
