| description | The synthesis of chloro -substituted liquid crystal containing azobenzene moieties was
carried out by coupling reaction and Williamson ether synthesis. The (4-(3-chloro-4-
acetylphenylazo)phenoxy) alkane were orange in colour which indicated the presence of
azo group. For characterization techniques of synthesized liquid crystal, differential
scanning calorimetry (DSC) was used to investigate the mesomorphic properties and its is
found that the (4-(3-chloro-4acetylphenylazo)phenoxy) hexane and (4-(3-chloro-4-
acetylphenylazo)phenoxy) decane to have mesophase. The structural investigation was
done by Fourier Transform Infrared (FT-IR) in KBr pellets and nuclear magnetic
resonance (NMR) with CDCl₃ as a solvent. Results show that the synthesized liquid
crystals have the functional group and the structure as expected |
