Abstract

original image

Two's complement: A series of discotic hydrogen-bonded complexes was prepared from a “clicked” triazole derivative with C3 symmetry and carboxylic acids (see picture; R1, R2=alkyl groups). Owing to the extended rigid core structure, the supramolecular discs could be stacked on top of each other, leading to hexagonal columnar liquid-crystalline phases.
