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 (a) containing azo, amido and Schiff bases was designed and synthesized. Its structure was characterized by 1H NMR, IR, MS and elemental analysis. Fluorescence spectroscopy showed that 1 had the largest peak at λex / λem = 370 nm / 422 nm; 1 the fluorescence quenched significantly when complexed with Cu2 +.
