A universal strategy for multicolor organic circularly polarized afterglow materials with high dissymmetry factors.

ABSTRACT: Materials with pure organic circularly polarized afterglow (CPA) have attracted significant attention due to their spatiotemporal-resolved optical properties, yet achieving simultaneous high dissymmetry factor (glum) and multicolor ultralong emission remains a challenge. Here, we establish a universal energy transfer-photon coupling strategy to realize CPA spanning from blue to red with record-high glum (up to 1.90) and ultralong lifetimes (>6 s). Systematic characterization of nonchiral donor-acceptor systems (TP-BPEA, TP-Fluo, etc.) reveals the absence of ground-state chiral centers (g_CD ≈ 0) and orientation artifacts (LD < 10^-7), confirming the key role of cholesteric liquid crystal polymer in chirality induction. This spatiotemporal synergy between e
