Addition of 1-alky1-3-methyl-imidazolium (C(n)-mim) cations 3-5 to a mixture of his-phosphonium cation 2 and sodium p-sulfonatocalix[4]larene (I) in the presence of lanthanide ions results in the selective binding of an imidazolium cation into the cavity of the calixarene. The result is a multi-laye...
