A new Janus system with liquid crystal properties was synthesized based on units derived from cyanoazobenzene and benzyl ether in its hemispheres, linked by a hydrazide group. The final compound and precursors with liquid crystal properties showed a nematic mesophase. Its mesomorphic properties were studied by polarized light microscopy and DSC. Cis/trans isomerization of the azo group in solution and liquid crystal state was studied using UV-Vis spectroscopy.
