Creating circularly polarized organic afterglow systems with elevated triplet energy levels, suppressed non-radiative transitions, and effective chirality—three critical prerequisites for achieving blue circularly polarized afterglow—has posed a formidable challenge. This work unveils a straightforward approach to attain blue circularly polarized afterglow materials by covalently self-confining isolated chiral chromophores within a polymer matrix. Robust hydrogen bonds within the polymer matrix create an isolated and stabilized molecular state, resulting in blue emission (414 nm), a 3.0 s lifetime, and a luminescent dissymmetry factor of −10⁻². Synergistic afterglow and chirality energy transfer, achieved by doping colorful fluorescent molecules into the blue polymers, enables full-color circularly polarized afterglow systems with versatile applications. This streamlined design expands the horizons of circularly polarized afterglow materials.
