Giant Circularly Polarized Luminescence Driven by Excited-State Hybridization Between Molecular Emitters and Chiral Environments.

ABSTRACT: Circularly polarized (CP) light is extensively used in various fields such as asymmetrical synthesis, sensing, and advanced displays. Consequently, significant efforts have been made to develop chiral materials that intrinsically emit CP light with a large dissymmetry factor (g-factor). It is widely considered that the dissymmetry factor for individual organic emitters, due to the amplitude offset between their electric and magnetic transition dipole moments, is limited to ≈10^-2, which is inadequate for practical applications. Recent efforts to enhance CP light emission have therefore focused on amplifying the dissymmetry of circularly polarized luminescence (CPL), often via specific energy transfer processes. Here, a fundamental mechanism is discovered - excited-state hybridiza
