Abstract

A molecular cage, macrobicycle 2, containing amide and pyrrole groups as hydrogen-bonding donors and imine groups as hydrogen-bonding acceptors has been synthesized. Compound 2 was found to recognize tetrahedral oxyanions with high affinities, such as HPO, HSO, SO, and HPO, as well as the spherical halide anions, in chloroform. A single-crystal X-ray diffraction analysis revealed that compound 2 formed a 1:1 complex with HPO in the solid state.

摘要

已合成了一种分子笼状大环化合物2，它含有作为氢键供体的酰胺和吡咯基团以及作为氢键受体的亚胺基团。发现化合物2在氯仿中能以高亲和力识别四面体氧阴离子，如HPO、HSO、SO和HPO，以及球形卤化物阴离子。单晶X射线衍射分析表明，化合物2在固态下与HPO形成了1:1的配合物。
