Click Chemistry Applied in the Synthesis of Symmetrical Triphenylene-Based Discotic Liquid-Crystalline Dimers

摘要

Symmetrical triphenylene dimers connected by a bis-triazole moiety have been synthesized and characterized. The bis-triazole part is formed as final step utilizing a straightforward double click reaction (CuAAC) allowing further structural variations of the linker. The 1,3-bis(triazol-l-yl)propyltriphenylene-based dimer display columnar mesophase over a wide range of temperatures starting at ambient temperature.
