新型生色杯[4]芳烃衍生物的合成及其对Cu^(2+)的识别

Synthesis and Recognition on Cu^(2+) of Novel Chromogenic Calix[4] arene Derivative

设计并合成了含偶氮基、酰胺基和席夫碱基的新型生色杯[4]芳烃衍生物(1),其结构经1H NMR,IR,MS和元素分析表征。荧光光谱研究表明,1在λex/λem=370 nm/422 nm处有最大峰;1与Cu2+配合时荧光显著猝灭。

A new chromogenic calix[4]arene derivative containing azo-groups,amide groups and Schiff-base groups was designed and synthesized.The structure was characterized by 1H NMR,IR,MS and elemental analysis.Fluorescence spectra test exhibited that λex/λem of 1 were 370 nm/422 nm.The fluorescent intensities could be quenched remarkably when 1 and Cu2＋ coordination.
