Circularly polarized luminescence from oriented polymer films doped with a tetraphenylethylene-based conjugated oligomer

Oriented polymer films fabricated by photopolymerization of cholesteric liquid crystalline mixtures doped with a tetraphenylethylene-based conjugated oligomer can emit strong yellow-orange CPL with absolute g_lum values up to 0.77 and Φ_F up to 60.4%.
