Abstract:

Recently, columnar materials have acquired great attention due to their potential technological applications. The introduction of a thiadiazole ring within the main structure opens the possibility of generating new mesogenic units. It causes changes in the polarity, polarizability and geometry, due to the associated dipole moment. In this work we report the synthesis and mesomorphic properties of new columnar liquid crystals with benzene and/or triazine cores and three pendant n-alkoxyphenyl- 1,3,4-thiadiazole arms (Ia-b and IIa-b respectively). The synthetic route is shown in scheme 1.
