采用核磁共振滴定法研究了四（苯脲）杯芳烃在1,3-交替构象中的络合行为。发现这种具有两个可能结合位点的受体表现出强烈的负变构效应，导致仅一个阴离子的排他性络合。2001爱思唯尔科学有限公司版权所有。
The complexation behaviour of tetrakis(phenylureido)calix[4]arene in the 1,3-alternate conformation has been studied using NMR titration experiments. It was found that this receptor with two possible binding sites exhibits a strong negative allosteric effect which leads to the exclusive complexation of only one anion.
