Controlling the organization of phosphonium cations relative to p-sulfonatocalix[4]arene anions

Abstract

Solution mediated organization of p-sulfonatocalix[4]arene, benzyltriphenylphosphonium cations, and bis(triethylammoniomethyl)-benzene dications in the solid state results in the ammonium dications preferentially binding in the cavities of two opposing calixarenes which take on a −3 charge, with the phosphonium cations arranged in a separate 2D sheet relative to the calixarene bilayer.
