Abstract

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-1-yl)propyltriphenylene-based dimer display columnar mesophase over a wide range of temperatures starting at ambient temperature.

Key words

discotic - columnar mesophase - liquid-crystal dimer - triphenylene - click chemistry - azide-alkyne cycloaddition

    We obtained 43% yield in our best trial for the synthesis of 6 instead of 94% as previously described by Kumar and Manickam.¹²d Moreover, Waldvogel¹³b has previously mentioned the similar impossibility to reproduce the yield described by Kumar and Manickam with the same procedure.
