Abstract A photo-responsive metallomesogen containing azobenzene (abbreviated as PRM) was synthesized to fabricate an optically and electrically tunable polarized light modulator. On basis of diffraction results with thermal and morphological ones, it was found that PRM formed a highly ordered smectic crystal phase. In addition, PRM showed excellent solubility in LC media. For polarized light modulator, PRM-filled IPS cell is fabricated and characterized. Reorientation direction of PRM induced by the in-plane electric field made absorption intensity of the polarized light high. When aligned direction of PRM is parallel with the polarized direction of light, the absorbance is increased. Furthermore, the absorption properties of PRM-doped optical cell is changed depending on wavelengths of the light. Because of azobenzene, the alignment of PRM break under ultra-violet irradiation. It makes the adsorption intensity low. Under visible light, the alignment of PRM return and the adsorption intensity is increased.
