Boosting circularly polarized luminescence by optimizing off-centering octahedral distortion in zero-dimensional hybrid indium-antimony halides.

ABSTRACT: Chiral zero-dimensional hybrid metal halides (0D HMHs) are being extensively studied as they can directly generate circularly polarized luminescence (CPL) with high photoluminescence quantum yields (PLQYs), yet improving their luminescence dissymmetry factor (g _lum) remains a challenge. This study proposes a general strategy to boost the g _lum value of chiral 0D HMHs by optimizing the off-centering distortion of inorganic octahedra. Accordingly, (R/S-MBA)₂(2MA)In_0.95Sb_0.05Cl₆ (MBA = α-methylbenzylammonium, 2MA = dimethylamine) and (R/S-MBA)₂(3MA)In_0.95Sb_0.05Cl₆ (3MA = trimethylamine) with near-unity PLQYs are accordingly synthesized.
