Zero-dimensional (0D) organic–inorganic metal halides (OIMHs) have emerged as a fascinating class of materials, offering unprecedented opportunities for the development low-cost solid-state lighting devices. Herein, we report two novel 0D Bi/Sb-based OIMHs, (2-ABI)3MCl6·H2O (M = Bi, Sb), crystallizing in monoclinic P21/n space group. Under 365 nm UV light irradiation, Sb-analogue displays bright and broad yellow emission band at 580 with photoluminescence (PL) quantum yield 34.6%, which may be attributed to distortion-induced self-trapped excitons (STEs). Theoretical study (2-ABI)3SbCl6·H2O ground state excited shows specific bonds are distorted significantly indicating role stereoactivity 5s2 lone pair. To understand effect gradual Sb substitution on structure optical properties (2-ABI)3BiCl6·H2O, series mixed compounds, (2-ABI)3Bi1–xSbxCl6·H2O (refined x 0, 0.11, 0.40, 0.53, 0.87, 1) was prepared. This work provides important insight into correlation between PL local distortion states induced by expression lone-pair electrons Sb3+, thus providing an efficient tool exploring highly emissive OIMHs further modulating their structures enhance luminescent practical optoelectronic applications.

Abstract Low‐dimensional hybrid organic‐inorganic metal halides (OIMHs) have attracted considerable attention in anti‐counterfeiting due to their non‐toxicity and high photoluminescence quantum yield (PLQY). However, many reported OIMHs are either not reversible or a poor PLQY. In this study, two antimony‐based halides, (C 21 H P) 2 SbCl 5 22 24 , synthesized using different organic cations. Both compounds exhibit bright orange–yellow emissions with PLQY of 82.6% 83.5%, respectively. The emission attributed the radiative recombination self‐trapping excitons. While maintains stable luminescence when exposed ethanol, undergoes structural transformation non‐luminescent Sb Cl 8 upon ethanol treatment, which can be reverted its luminescent state by heating. Even after multiple cycles, is still over 80%, demonstrating excellent cycling stability. also explored as fluorescent materials for Morse code optical logic gate applications. This work offers completely new option material used security information.
