“…This factor is determined by the equation g lum = 2( I L – I R )/( I L + I R ), where I L and I R represent the intensities of left- and right-handed CPL emission, respectively. However, the practical application of CPL materials is hindered by the inability of existing CPL materials to achieve sufficiently high dissymmetry factor ( g lum ) values. − To date, several strategies have been developed for high-performance CPL materials, including chiral supramolecular assemblies such as liquid crystals (LCs), , Förster resonance energy transfer (FRET), − triplet–triplet annihilation-based photon upconversion, , and helical polymers. − Notably, cholesteric liquid crystals (CLCs) have received particular attention due to their unique optical capability to generate CPL with significantly high g lum values through selective reflection or chiral supramolecular coassembly. , …”
