Abstract

A series of new triphenylene discotic liquid crystals has been synthesized by a straightway and the influence of molecular symmetry and chain length on the mesomorphism investigated. The symmetrical compounds 1, 3, 7, 11-trimethoxytriphenylene-2, 6, 10-triyl tris (3, 4, 5-tris (alkyloxy) benzoate), with alkyl chain lengths of C7, C8, C10, and C12, and the unsymmetrical compounds 2 were studied by using polarized optical microscopy (POM), ...
