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。
New calix[ 4 ] arene poly （aza） derivatives 3, 4 and bis-calix [ 4 ] 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[4 ] arene derivatives containing amido and Schiff-base groups.
