“…With respect to the development of alternatives for toxic Pb 2+ , much attention has been concentrated on Sn 2+ , Ge 2+ , and Cu + . − Though they endow corresponding OIMHs with comparable performance to lead analogues, their susceptibility to oxygen brings challenges of stability in air. Recently, the antimony/bismuth halides came into vision for Sb 3+ and Bi 3+ possess similar outermost electronic configurations (5s 2 5p 0 /6s 2 6p 0 ) to Pb 2+ , and they often exhibit enhanced stability to air. − However, their hydrolyzability raises concerns about their usability in humid environments.…”

Zero-dimensional (0D) organic−inorganic hybrid metal halides (OIMHs) have been a category of non-negligible candidates with potential application in light-emitting diodes (LEDs), optical information storage, and anticounterfeiting. Herein, we first obtained two 0D isomorphic indium-based OIHMs, namely, IBPAInCl 6 •H 2 O and IBPAInBr 6 •H 2 O (IBPA 3+ = bis(3-aminopropyl)amine cation), and further prepared a family of crystal samples of mixed-halogen IBPAIn(Cl 1−x Br x ) 6 •H 2 O (x = 0.25, 0.5, and 0.75) with the strategy of halogen substitution, which integrated the bluish-white photoluminescence (PL) emission of IBPAInCl 6 •H 2 O and the orange PL emission of IBPAInBr 6 •H 2 O as a perfect pair of complementary colors affording white-light emission. Interestingly, the cold-warm-tunable whitelight emission in single-metal-templated In-based OIMHs was realized for the first time via continuous halogen content control. Mechanistic studies disclose that the ratios of the emission intensities at higher energies and lower energies present a gradual variation tendency, resulting in cold-warm-tunable white-light emissions. Moreover, the ultralong afterglow of IBPAInCl 6 •H 2 O (1.1 s) that can be identified by the naked eyes was found to be facilely tuned by regulating the content of Br − anions. Hence, the crystal samples of halogen substitution in In-based halides were applied as anticounterfeiting/information storage materials to fabricate a time-resolved encryption system with high performance.

Chiral organic‐inorganic hybrid lead halides have recently attracted great attention due to their unique chirality and diverse functional properties. However, they suffer from highly toxic lead, while lead‐free chiral hybrid metal halides especially those with phase transitions remain sparse. Here, we report a new lead‐free chiral metal halide crystal [R‐3‐fluoropiperidinium]2SbCl5 ([R‐3‐FPP]2SbCl5), which crystalizes in chiral P212121 space group at 293 K and consists of chiral [3‐FPP]+ cations and one‐dimensional [SbCl5]n2‐ zigzag chains of corner‐sharing SbCl6 octahedrons. Notably, [R‐3‐FPP]2SbCl5 undergoes an above room temperature phase transition at 313 K, which can be attributed to the order‐disorder transition of both the organic [R‐3‐FPP]+ cation and inorganic [SbCl5]2‐ anions. In addition, [R‐3‐FPP]2SbCl5 also shows a broad band gap of 3.36 eV. This work promotes the exploration of chiral lead‐free hybrid lead halides with phase transitions.
