The development for display devices with highly efficient and energy-saving is more and more being required. For that reason, a dicyanodistyrylbenzene-based efficient emissive reactive mesogen (abbreviated as D-DRM) was newly synthesized. Polymer-stabilized D-DRM thin films not only have excellent LPL property but also show strong emission. The maximum intensity of the D-DRM polymer film was recorded at 545 nm, and the intensity was affected by the angle between the direction of the polarizer and the orientational direction of the luminogen thin film. However, minimum intensity was recorded when T has a vertical alignment about OD. About 60 % of the emitted light from polymer film is transmitted while the polarizer transmits about 40 % of the unpolarized light. Consequently, the highly efficient emissive thin films with LPL property are fabricated from alignment of AIE luminogen.
