Heuristics for precise supramolecular control of soft matter structure and properties – 2,3,4-tris(dodecyloxy) benzenesulfonates with Alkaline and Organic Cations

Abstract

Comparative analysis of the effect of driving forces on the self-assembly of a materials phase behaviour for a number of 2,3,4-tris(dodecyloxy) benzene sulfonates with alkali metal and organic focal groups have shown that the shape of the mesogenic group plays a decisive role in phase behaviour of the material. Cubic and layered types of packing prevail when the size of the cation is small and, thus, the shape of the mesogenic molecule is close to conic one. With increasing cation size, the shape becomes more tapered, and columnar mesophases appear to be more stable. Special interactions of focal groups however determine the temperature range of stability of one or another mesophase. Comparatively strong their interactions may, however, provide substantial deviations from a phase diagram plotting the transition temperatures versus the radius of focal group, as in the case of pyridinium 2,3,4-tris(dodecyloxy) benzene sulfonate.
