Hexagonal Columnar Superstructure Generated by Compact Liquid-crystalline Molecules Possessing Disk-shape, C3-Symmetry, and Ionic Bonding Sites

Small C 3 -symmetric supramolecules, 1:3 complexes of tri(2-aminoethyl)amine (1) and 3,4,5-trialkoxybenzoic acid (2c-2n, R = (CH 2 ) n-1 CH 3 , n = 5-16) generated a stable hexagonal columnar phase. The phase behaviors, stoichiometry, supramolecular structure, and superstructure were investigated.
