文摘

A series of novel calix[4]arenocrowns 1a–c were efficiently synthesized by a one-pot reaction of calix[4]monohydroquinone diacetate 5 with ditosylate 6 and its analogues in the presence of sodium hydroxide. It was found that the calix[4]arenocrowns could form stable pseudorotaxane-type complexes 2a–c with paraquat, and further self-assemble into calix[4]areno[2]catenanes 3a–c with dicationic salt 8 and p-bis(bromomethyl)benzene.
