Linearly polarized light emissive organic materials with great processability are essential to development of advanced optical devices. To fabricate polymerized liquid crystalline thin films with linearly polarized luminescence (LPL) property, a dicyanodistyrylbenzene-based reactive mesogen (abbreviated as DCRM) was newly designed and synthesized. Based on the morphological observations with thermal and optical analysis, it was realized that DCRM has a nematic mesophase. DCRM molecules were polymerized by thiol-ene click reaction. Due to chemically crosslinked structure, the DCRM polymer thin films had extreme stability under thermal, mechanical and chemical stimuli. The uniaxially oriented polymer thin films with aggregation-induced emission (AIE) property showed not only powerful emission but also noticeable LPL property.
