Abstract The combination of Sn II or Sb III with π, non‐π‐conjugated units has produced birefringent crystals birefringence ranging from 0.005 to 0.468@1064 nm. It is proven that introducing into a feasible strategy enlarge the birefringence, which not only promotes miniaturization fabricated devices, but also effectively modulates polarized light. Herein, recently discovered , ‐based investigated are summarized, including their crystal structure and optical properties, especially birefringence. This review presents influence stereochemically active lone pair on anisotropy. We hope this work provides clear perspective chemistry functional development new large

Low-dimensional organic-inorganic hybrid metal halide materials have attracted widespread attention due to their excellent and tunable photoelectric properties. However, the low intrinsic photoluminescence quantum yields (PLQYs) limit further applications in optoelectronic devices. Here, we report synthesis of lead-free zero-dimensional indium chloride crystals, (FA)3InCl6: xSb3+, with strong red-light emission through controlled Sb3+ doping. The optimal composition, 20.16% Sb3+, exhibits PLQY up 30% emits red broadband light centered at 690 nm. enhancement doped samples was investigated by combining temperature-dependent wavelength-dependent spectra, revealing self-trapped exciton (STE) recombination process. clear elucidation complexation process has provided a solid theoretical basis for optimization material properties, which is great significance development new light-emitting materials. Far-red phosphor-converted LED devices been constructed these demonstrate stable efficient various voltages, exhibiting superior stability.
