[图表]通过脲基官能团将四苯基卟啉单元嵌入杯[4]芳烃骨架导致设计用于通过紫外-可见光谱进行阴离子和/或阳离子检测的新型阴离子受体。杯芳烃在锥形或1，3-交替构象轴承上边缘上的两个脲基部分代表良好的预组织腔，其中阴离子可以通过与NH基团的同步氢键相互作用。
[GRAPHICS]Appending tetraphenylporphyrin units to the calix[4]arene skeleton via the ureido function leads to novel anion receptors designed for anion and/or cation detection by UV-vis spectroscopy. Calixarenes in the cone or 1,3-alternate conformations bearing two ureido moieties on the upper rim represent well-preorganized cavities where the anion can be held by synchronous hydrogen bonding interaction with the NH groups.
