Abstract
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 <italic>g</italic><sub>lum</sub> values up to 0.77 and <italic>Φ</italic><sub>F</sub> up to 60.4%.
