Abstract
Three solid-state supramolecular structures were obtained by inclusion complexation of p-sulfonatocalix[5]arene with 1,2-bis(4,4′-methylpyridinium)ethane, 1,2-bis(4,4′-aminopyridinium)ethane and 1,4-bis(pyridinium)butane. All three complexes have been thoroughly examined from the aspects of binding mode, stoichiometry and extended structure. Effects of guest molecules, especially spacers and terminal groups, on host conformation, binding and extended structures were carefully compared and summarized.
