An investigation of the synthesis of chiral LCs based on the [1,2,3]‐triazole ring

Abstract

The design and synthesis of chiral liquid crystalline compounds based on the [1,2,3]‐triazole heterocycle using the click chemistry modular approach is presented. The target compounds showed LC phases of type SmA, SmC* and helical N* (cholesteric). Mesomorphic behaviour was determined by polarizing optical microscopy and differential scanning calorimetry. Contact experiments indicated a right‐handed helix for the macrostructure of the cholesteric phase.
