摘要
以邻、间、对氨基苯甲酸和杯 [4]芳烃为原料 ,经重氮化 -偶联反应合成了发色邻、间、对羧基苯偶氮基杯 [4]芳烃 ,产物的结构经 IR,1H NMR和元素分析表征 ;研究了它们的生色原理和光谱性能。结果表明它们是一类新型指示剂和具有新型配位空腔的主体分子。
The synthesis of new chromogenic p (o,m,p carboxylazo) calix [4] arenes derivatives through the coupling of diazotized o,m,p aminobenzene carboxylic acid and calix [4] arenes is described. Their structures were confirmed by IR, 1H NMR and elemental analysis. Their chromogenic properties and UV vis absorption spectra were investigated under different pH conditions. Experimental results show that the synthesized derivatives can be used as new indicators and host molecules.
