Abstract

A macrocyclic compound alternatingly composed of three pyridine and three benzyl alcohol units linked with acetylene bonds was developed as a new type of D3h-symmetric hexagonal shape-persistent macrocycles with a host function. The macrocycle was prepared via several steps of Sonogashira reaction and proved to interact with halide anions, especially chloride on the basis of 1H NMR studies.
