Circularly Polarized Phosphorescence Energy Transfer Combined with Chirality‐Selective Absorption for Modulating Full‐Color and White Circularly Polarized Long Afterglow

Circularly polarized long afterglow (CPLA) attracts great interests in multi-disciplinary fields with significant potentials in optical multiplexing applications, but achieving full-color and white CPLA is still challenging. The present contribution reports the first success in utilizing circularly polarized phosphorescence energy transfer (CPP-ET) combined with chirality-selective absorption (CSA) to construct full-color and white CPLA materials. Blue CPLA with luminescence dissymmetry factor (g
