Abstract
Thermotropic liquid crystalline polyazomethines containing 1,3,4‐oxadiazole chromophors have been synthesized. These polymers are semiflexible liquid crystalline compounds containing luminescent mesogens. Thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), polarized optical microscopy (POM), and wide angle X‐ray diffraction (WAXD) have been used to evaluate their thermal and mesomorphic properties. The target polyazomethines present liquid crystalline behavior with classical calamitic textures, large mesophase range, and high thermal stability. The investigation of the optical properties of the synthesized polymers, in solution and solid state, confirmed a blue fluorescence.Keywords
