Constructing 2D porous material based on the assembly of large organic ions: p-sulfonatocalix[8]arene and tetraphenylphosphonium ions
Abstract
In the presence of tetraphenylphosphonium and aquated ytterbium(III) ions, conformationally flexible p-sulfonato-calix[8]arene forms an extended structure with two dimensional porosity involving the assembly of phosphonium
