An acid-base-responsive supramolecular host-guest system based on a planarly chiral A1/A2-diamino-substituted pillar[5]arene (1)/imidazolium ion recognition motif was created. The pillar[4]arene[1]diaminobenzene 1 can bring an electron-deficient imidazolium cation into its cylindrically shaped cavity under neutral or basic conditions and release it under acidic conditions.
构建了一种基于平面手性A1/A2-二氨基取代的柱[5]芳烃（1）/咪唑鎓离子识别基序的酸碱响应超分子主客体体系。柱[4]芳烃[1]二氨基苯1能够在中性或碱性条件下将缺电子的咪唑鎓阳离子带入其圆柱形空腔，并在酸性条件下将其释放。
