Abstract Due to the circularly polarized luminescence (CPL) and high efficiency, chiral phosphorescent complex holds promise for CP organic light‐emitting diode (CP‐OLED) 3D display, but application of manganese(II) (Mn(II)) is rare. Herein, CP‐OLEDs with Mn(II) enantiomers, R / S ‐DFPO‐MnBr 2 ‐XTDPO‐MnBr , based on tert ‐butyl(6‐(diphenylphosphoryl) dibenzo[ b d ]furan‐4‐yl)(phenyl)phosphine oxide ‐butyl(5‐(diphenylphosphoryl)‐9,9‐dimethyl‐9 H ‐xanthen‐4‐yl)(phenyl) phosphine ligands are reported containing phosphorus‐centered point chirality. exhibit yellow‐green emissions peaking at 541 532 nm photoluminescence quantum yields up 87%, CPL spectra dissymmetry factors (| g PL |) around 2.0 × 10 −3 . The achieve external efficiencies 12.9% electroluminescence | EL values about 1.8 10⁻ 3 suggesting potential complexes.

While anticounterfeiting systems based on long persistent luminescence (LPL) materials demonstrate a mature trend, the integration of tunable luminescent lifetimes and emission colors in LPL-based remains challenge. Herein, we propose temporal spatial strategy utilizing novel zero dimensional (0D) metal halides, specifically (PBA)3BiCl6:xSb3+ (PBA = 4-Phenylbenzylamine, x 0, 0.05, 0.1, 0.15), which exhibit characteristics. A controllable color transition can be observed from green to white orange by varying excitation wavelength, accompanied different afterglow durations LPL emission. Additionally, various are at delay times. Furthermore, controlled duration is achieved through Sb3+ doping (PBA)3BiCl6, attributed triplet energy transfer (TET) process. noticeable when using mobile phone's flashlight as source, enhancing portability light source. The multifaceted tuning modulation establish foundation for multicolor time-resolved anticounterfeiting, significantly elevating security level advanced portable systems.
