Abstract Achieving narrowband emission, high efficiency, and circularly polarized luminescence (CPL) in organic light‐emitting diodes (OLEDs) remains a significant challenge. In this study, discrete supramolecular dimerization strategy is presented to overcome limitation. By incorporating helical arylamine with sterically demanding configuration into multi‐resonance emitter, the formation of unique dimeric structure solid state enabled. Unlike conventional emitters prone aggregation‐caused quenching continuous stacking, CPL form discrete, well‐separated dimers. This distinct arrangement not only preserves photoluminescence quantum yield emission but also amplifies signals by optimizing intermolecular electronic coupling. OLEDs these enantiomers at 10 wt.% doping level exhibit outstanding performances, including narrow full‐width half‐maximum 30 nm, maximum external efficiencies (EQE) 33.5% 32.4%, impressive electroluminescence dissymmetry factors ( g EL ) +8.7 × −3 −9.1 , respectively. Remarkably, increasing concentration 20 further boosts values +1.6 −2 −1.8 . enhancement leads Figures Merit (EQE | |) 3.71 4.12 among highest for devices.

Organic photofunctional materials exhibit properties that are highly dependent on their structural hierarchy. The variability in intermolecular interactions and molecular packing both monomeric aggregated states complicates the controllability predictability of photophysical photochemical properties. To address this challenge, we developed three luminescent supramolecular [
