Formation of iminium ions during the processing of metal halide perovskites †
Ammonium ions are a key component of many organic–inorganic metal halide materials. We show that the hexagonal perovskite (Me2NH2)PbI3 is rapidly transformed to iminium-based perovskites (Me2C 00000000 00000000 00000000 00000000 11111111 00000000 11111111 00000000 00000000 00000000 NMeR)PbI3 (R = Me...

Summary: | Ammonium ions are a key component of many organic–inorganic metal halide materials. We show that the hexagonal perovskite (Me2NH2)PbI3 is rapidly transformed to iminium-based perovskites (Me2C 00000000 00000000 00000000 00000000 11111111 00000000 11111111 00000000 00000000 00000000 NMeR)PbI3 (R = Me, Et), simply by stirring the material in the respective ketone at room temperature, triggering clear changes in the materials’ photophysical properties. |
