多重氮杂杯[4]芳烃和双杯[4]芳烃的合成与阳离子萃取性能
Syntheses and Cations′ Extraction Properties of Poly(aza) Calix\arenes and Bis-calix\arene
【摘要】 合成了含有偶氮基、胺基、酰胺基和席夫碱基新型杯[4]芳烃多重氮杂衍生物3和4以及双杯[4]芳烃5,产率分别为87%、89%和84%。它们的结构经1H NMR、ESI-MS和元素分析表征确证。液液两相萃取实验表明,它们对阳离子有较好的萃取能力,比仅含酰胺基和席夫碱基的类似杯芳烃衍生物有明显提高。
【Abstract】 New calix\arene poly(aza) derivatives 3,4 and bis-calix\arene 5 containing azo-groups,amido groups and Schiff-base groups were synthesized in yields of 87%,89%,84%,respectively.Their structures were confirmed by 1H NMR,ESI-MS and elemental analysis.Liquid-liquid extraction experiments showed they possessed excellent extraction capabilities for cations and their extraction percentages were higher than those of(similar) calix\arene derivatives containing amido and Schiff-base groups.
