A kind of novel liquid crystalline monomer containing double photosensitive groups which were azo and chalcone groups was synthesized. The structures of the intermediates and the final monomer were confirmed by FT-IR and 1H NMR spectra. The thermal properties of monomer were measured by DSC and the liquid crystalline texture was measured by polarized optical microscopy. And the results indicated that the monomer showed nematic phase and liquid crystal temperature range was 150.8-186.5oC.
