Synthesis and Characterization of Photo-Responsive Thermotropic Liquid Crystals Based on Azobenzene
A series of new thermotropic liquid crystals (LCs) containing azobenzene units was synthesized. The structures of the compounds were characterized by means of NMR and FTIR spectroscopy. Their mesomorphic behaviors were investigated via differential scanning calorimetry (DSC) and polarizing optical m...
