A new
kind of supramolecular columnar liquid crystal T–A with a broad mesomorphic range (up to 164.9 °C), good thermal
stability, and strong fluorescence is designed and formed by the H-bonding
between 1,3,5-tri(1H-benzo[d]imidazol-2-yl)benzene
(T) and serial gallic acid derivatives (A). Two components are easily available because of simple routes,
common reactions, high yields, commercial starting materials, and
inexpensive catalysts. The introduction of the 1,2,3-triazole structure
into component A makes the textures different and is
slightly disadvantageous for the T–A complexes.
