Abstract Stimulus‐responsive materials that exhibit efficient circularly polarized luminescence (CPL) have gained much interest for application in advanced smart photonics. Herein, the CPL‐active enantiomorphic 0D Sb 3+ ‐doped (R/S) 2 InCl 7 (R/S = R/S‐2‐methylpiperazine) are synthesized via a solution method. They show broadband yellow emission with near‐unity photoluminescence quantum yield and CPL asymmetry factor of 1.7 × 10 −3 .

Chiral zero-dimensional hybrid metal halides (0D HMHs) could combine excellent optical properties and chirality, making them promising for circularly polarized luminescence (CPL). However, chiral 0D HMHs with efficient CPL have been rarely reported. Here, we propose an strategy to achieve simultaneously high photoluminescence quantum yield (PLQY) large dissymmetry factor (glum ), by integrating achiral ligands into HMHs. Specifically, three pairs of indium-antimony chlorides are synthesized combing guanidine types methylbenzylammonium-based derivatives as the organic cations. These exhibit near-unity PLQY glum values up around ±1×10-2 . The ligand is not only essential crystallize these PLQYs, but also greatly enhances chirality induction from inorganic units in Furthermore, choice different can modify strength hydrogen bonding interactions HMHs, maximize their values. Overall, this study provides a robust way realize expanding applications chiroptical fields.

Abstract Generating circularly polarized luminescence (CPL) with simultaneous high photoluminescence quantum yield (PLQY) and dissymmetry factor ( g lum ) is difficult due to usually unmatched electric transition dipole moment μ magnetic m of materials. Herein we tackle this issue by playing a “cascade cationic insertion” trick achieve strong CPL (with PLQY ~100 %) in lead‐free metal halides values reaching −2.3×10 −2 without using any chiral inducers. Achiral solvents hydrochloric acid (HCl) N, N ‐dimethylformamide (DMF) infiltrate the crystal lattice via asymmetric hydrogen bonding, distorting perovskite structure induce “intrinsic” chirality. Surprisingly, additional insertion Cs + cation substitute partial (CH 3 2 NH transforms space group achiral but maintains chiroptical activity. Further doping Sb 3+ stimulates as result self‐trapped excitons (STEs) formation disturbing framework. The perovskites indium‐antimony chlorides embedded on LEDs chips demonstrate promising potential emitters. Our work presents rare cases activity highly luminescent from only building blocks spontaneous resolution symmetry breaking.
