Abstract Circularly polarized luminescence (CPL) materials have attracted significant attention owing to their unique luminescent properties and broad range of applications. However, challenges remain, including controlling helical assembly, mitigating aggregation‐caused quenching, balancing quantum yield ( Φ PL ) with g values. Here, the study reports synthesis a novel asymmetric, spiranic O‐organoboranes bearing isoindolyl‐indolenine scaffold (BBI) axial chirality through BINOL substitution, as well its supramolecular assembly surfactant‐regulated tunable CPL behaviors. The newly designed BBI dye shows relative weak 10% in toluene. Supramolecular acetonitrile/water co‐solvents exhibit an obvious aggregation‐induced emission (AIE) process, leading formation spherical nanostructures red‐shifted orange‐yellow (554 nm, = 0.012, 7%). Moreover, surfactant sodium dodecyl sulfonate (SDS) can promote aggregation pure deionized water, producing nanofibers blue‐shifted yellow (536 0.006, 13%). Crystal growth toluene/hexane SDS aqueous/acetonitrile systems reveals chiral crystals P 212121 space group, offering insights into amplification. This demonstrates ability precisely control parameters, X‐ray single‐crystal analysis providing additional understanding regulation.
