The synthesis of [1,2,3]-triazole-based bent core liquid crystals via microwave-mediated ‘Click Reaction’ and their mesomorphic behaviour

ABSTRACT

A series of [1,2,3]-triazole-based liquid crystal compounds were synthesised via a fast and efficient microwave-mediated ‘Click Reaction’ and their phase behaviour is presented. Most of the 1,4-diaryl-[1,2,3]-triazole compounds exhibited a nematic phase with broad temperature ranges and relatively low transition temperatures compared to previously examined materials. Structural variations, involving regio-isomers and lateral halogenation, gave rise to different phase behaviour of the two families of triazole-based compounds.
