Lead Halide Perovskite Nanocrystals in Metal‐Organic Frameworks: Synthesis, Properties, and Applications

Halide perovskite nanocrystals (PeNCs) with their exceptional light absorption and tunable bandgap, are promising candidates for solar energy harvesting and high-performance photodetectors. However, the susceptibility of PeNCs to degradation limits their widespread application. The integration of halide perovskites within metal-organic frameworks (MOFs) has recently garnered significant attention as a strategy to create composite materials. The above encapsulation enhances the stability of perovskites against environmental stressors, such as humidity, temperature, and light, leading to improved performance characteristics. This paper provides a comprehensive review of perovskite-metal-organic framework composites (PeMOFs) and their applications in photoelectric conversion. It explores the various preparation methods for PeMOFs and highlights recent advancements in the field. The review examines the specific functions of MOFs within these composite materials and summarizes recent progress in a range of applications, including photocatalysis, sensing, light-emitting diodes, perovskite solar cells, luminescent anti-counterfeiting, information security, and detection. Finally, the paper discusses potential future trends and emerging applications for PeMOFs.
