Fluorous Ligands and their effect on Long Term Stability of Mixed Halide Perovskites |
| 초록 |
Stability is a major deterrent to the mainstream application of mixed halide perovskites. The ionic nature of halide perovskites makes them vulnerable in the atmosphere and in polar solvents. Herein, we report a one-pot synthesis of mixed halide perovskite QDs in the presence of fluorous fatty acids along with oleic acid (OA) and oleylamine (OAm). The introduction of fluorous acid is aimed at improving the environmental stability of QDs. The relative composition of fluorous fatty acids during synthesis influences the size, form and optical properties of QDs. Higher concentrations of fluorous acids lead to 2D perovskites. Temperature-dependent phase segregation between fluorous carboxylic acid and OAm leads to structure and color variation in synthesized nanomaterials. |
