Low-dimensional hybrid lead-free azetidinium metal halides

Year: 2025
Type: article
Abstract: Organic–inorganic hybrid halide perovskites have attracted attention in optoelectronics and photovoltaics. However, the Pb-content in the crystal structure and instability issues have raised questions about the industrialization of these materials. Bi and Sb are widely considered as an alternative on the B-site due to their isoelectronic configuration with the Pb divalent cation. Herein, we report four novel Pb-free azetidinium metal halides and present their fundamental material properties: [(CH2)3NH2]2AgBiBr6, [(CH2)3NH2]3Bi2I9, [(CH2)3NH2]3Bi2Br9, and [(CH2)3NH2]3Bi2Cl9. Our materials have a low-dimensional perovskite-like structure from 0 to 2D, where the replacement on the B-site is based on Ag+/Bi3+ and Bi3+. Graphical Abstract As a potential light absorber, four different azetidinium metal halides were successfully synthesized via evaporation. The polycrystalline powders and thin films of the azetidinium metal halides present low dimensionalities from 0 to 2D.
