Solid-state supramolecular architectures by p-sulfonatocalix[4]arene with bispyridinium derivatives

Abstract

Two supramolecular structures were obtained by inclusion complexation of p-sulfonatocalix[4]arene with 1,2-bis(pyridinium)ethane and 1,2-bis(4,4'-dipyridinium)ethane in single-crystal form, which have been examined from the aspects of binding mode, stoichiometry and extended structure. Effects of guest molecules, especially charges and terminal groups, on host conformation, binding and extended structures were carefully compared and summarized. © 2010 SIOC, CAS, Shanghai, & WILEY-VCH Verlag GmbH & Co.
