photodetectors and solar cells. However, their large size limits their processability and surface area, which is critical for applications like photocatalysis and light emission. In contrast, CPB NCs exhibit outstanding optoelectronic properties, such as high photoluminescence quantum yield, high charge carrier mobility, and high absorption coefficient in the visible light range. These materials are widely used in photocatalysis, fluorescence sensing, and optoelectronic devices. Despite these promising features, one of the most critical challenges for CPB NCs remains their stability. The ionic crystal structure makes them less resistant to chemical and physical vulnerabilities such as heat, polar solvents, light, and oxygen. CPB NCs are highly sensitive to polar solvents and harsh reaction environments, which can lead to rapid degradation. Researchers have explored various strategies, including surface passivation, encapsulation, and interface engineering, to address the instability of perovskite-based devices and extend their operational lifespan. In this context, metal-organic frameworks (MOFs) have emerged as a promising approach to significantly enhancing CPB stability by encapsulation. Structurally, MOFs consist of single or mixed metal ions coordinated with organic linkers (ligands) to form a porous framework, enabling applications in gas storage, supercapacitors, and photocatalytic dye degradation. The MOF materials pose high crystallinity, large surface area, excellent porosity, and remarkable environmental stability. Thus, these materials can effectively shield CPB from external environmental factors by providing a protective barrier, thereby reducing degradation and improving long-term performance. Furthermore, MOFs are among the most effective catalysts for photocatalysis due to their large surface area and strong lightharvesting ability. These properties significantly enhance the performance of CPB-MOF-based nanocomposites, particularly in photocatalytic applications. Typically, MOFs synthesized under mild conditions are preferred for composite formation with CPB NCs to prevent their degradation under harsh conditions. Zeolitic Imidazole
