Hierarchical study of mono- and multicharged imidazolium encapsulation in p-sulfonatocalix[4]arene molecular capsules

Abstract

Four ternary multi-component crystal structures comprising water-soluble p-sulfonatocalix[4]arene anion as the cavitand in the presence of different types of positively charged guest molecules comprising 1-butylimidazolium, 3,3'-(1,4-phenylenebis(methylene))bis(1-methylimidazolium), 3,3',3''-(benzene-1,3,5-triyltris(methylene))tris(1-methylimidazolium), or 3,3',3'',3'''-(benzene-1,2,4,5-tetrayltetrakis(methylene))tetrakis(1-methylimidazolium) and...
