Systematic rim cyano functionalization of pillar[5]arene and corresponding host−guest property varieties

Abstract

Synthetic investigation of systematic replacement of alkoxy groups in pillar[5]arene by cyano ones was carried out. nCN-pillar[5]arenes(n = 2, 4, 6, 8 or 10) bearing different numbers of cyano functions on their rims were successfully prepared for the first time. Single-crystal X-ray diffraction studies showed that the nCN-pillar[5]arenes had unique conformations in the solid states. Besides, host−guest property studies of those nCN-pillar[5]arenes and 1,4-dicyanobutane showed the functionization number related host−guest interaction varieties.
