To fabricate polarized light emissive polymer film, we newly designed and synthesized a dicyanodistyrylbenzene-based reactive AIEgen (DDRL) containing thiol and vinyl units. Based on the microscopic methods with thermal and scattering ones, it was realized that DDRL has a nemaic mesophase and is uniaxially oriented by surface anchoring of alignment layer. Uniaxially oriented and polymer-stabilized DDRL film was fabricated by thiol-ene reaction of DDRL in anti-parallelly rubbed optical cells. The fabricated DDRL polymer film exhibited polarized light emission with excellent stabilities. The polarization ratio and order parameter of DDRL polymer film were 2.25 and 0.29, respectively. The polymer-stabilized films obtained from reactive AIEgens can provide new perspectives about linearly polarized luminescent polymer films.
