N2 - Due to the circularly polarized luminescence (CPL) and high efficiency, chiral phosphorescent complex holds promise for CP organic light-emitting diode (CP-OLED) and 3D display, but the application of chiral manganese(II) (Mn(II)) complex is rare. Herein, the CP-OLEDs with Mn(II) enantiomers, R/S-DFPO-MnBr2 and R/S-XTDPO-MnBr2, based on tert-butyl(6-(diphenylphosphoryl) dibenzo[b,d]furan-4-yl)(phenyl)phosphine oxide and tert-butyl(5-(diphenylphosphoryl)-9,9-dimethyl-9H-xanthen-4-yl)(phenyl) phosphine oxide ligands are reported containing phosphorus-centered point chirality. R/S-DFPO-MnBr2 and R/S-XTDPO-MnBr2 exhibit yellow-green emissions peaking at 541 and 532 nm with photoluminescence quantum yields of up to 87%, CPL spectra with dissymmetry factors (|gPL|) around 2.0 × 10−3. The CP-OLEDs achieve external quantum efficiencies of up to 12.9% and CP electroluminescence spectra with |gEL| values of about 1.8 × 10⁻3, suggesting potential application of chiral Mn(II) complexes.
