We have successfully prepared 5-(2-phenylethynyl)isophathalilc acid as a signaling unit and the corresponding derivatives for an anion receptor 2 and a barbiturate receptor 4. Receptor 2 showed characteristic UV–vis changes and dramatic fluorescence quenching upon the addition of anions and receptor 4 showed UV–vis and an OFF-ON fluorescence changes upon the addition of dibutylbarbituric acid based on the diphenylethyne moiety.

通过带有苯基乙炔基的间苯二甲酰胺受体的紫外可见和荧光检测

我们已经成功地制备了5-（2-苯基乙炔基）异邻苯二酸作为信号传导单元，以及相应的阴离子受体2和巴比妥酸酯受体4的衍生物。受体2表现出特征性的UV-vis变化，加入阴离子后荧光急剧淬灭，受体4表现出UV-vis且基于二苯基乙炔部分添加二丁基巴比妥酸时OFF-ON荧光变化。
