Anion Guided Self-Assembling of Guaninium Cations

Babulal Das and Jubaraj B Baru

Abstract

Anions guide self-assemblies of ribbons or end-capped dimers of guaninium cations. Self-assemblies of several salts of guanine are compared with related guanine salts from literature. End-capped dimers of guaninium cations selfassembled by perchlorate or by dihydrogen-phosphate anions whereas sulphatebisulphate anions stabilizes infinite ribbon-like assemblies of cations. Formation of discrete, dimer, or ribbons of cations in guaninium salts depends on anions and water has less dominant role other than to modify environments of anions. This result is a contrast effect caused by aquation on self-assembilies of neutral guanine molecules.
