“…The 2D perovskite can be formed by alternating A and [B 2 X 5 ] À layers for AB 2 X 5 [25] or alternating [BX 6 ] 4À octahedras and large cation A for A 2 BX 4 or A 3 B 2 X 9 . [26,27] Generally, the 2D perovskite family is built upon the chemical slicing of 3D perovskite along (100), (110) and (111) crystal planes, yielding A 0 2 A n-1 B n X 3nþ1 , A 0 2 A m B m X 3mþ2 , and A 0 2 A q-1 B q X 3qþ3 , respectively. [28] The 3D perovskite also includes the A 2 B þ B 03þ X 6 -type structure, which is called double perovskite, [29] and the corresponding layered 2D perovskites.…”

Scientific and industrial interest on perovskite semiconductor materials has grown rapidly in recent years. Through the efforts of researchers professionals in chemistry, physics, materials and electronics, etc., many records based on perovskites have been and are being refreshed. The brilliant performances emerge not only from the excellent properties of perovskite themselves, but also originate from the composite material systems of hybridizing perovskites with heteromaterials. Herein, first, the crystal and nanostructures of perovskite materials, semiconductor-based heterojunctions, and the categories of perovskite heterojunction are fundamentally introduced. Then, the state-of-the-art synthesis methods, size and structure control, electron structure-related physical properties, and applications of the perovskite-based nano-heterojunctions are comprehensively reviewed. Finally, perspectives on tackling challenges and developing trends are discussed.

This Review examines how the intermarriage of perovskite and metal‐organic framework crystals brings new paradigms for material design and functionality. The strategic combination of halide perovskites and metal–organic frameworks (MOFs) has generated a new family of porous composite materials that will enable new applications, including optoelectronic, catalysis, sensing, and data encryption. This Review surveys the current progress of this exciting new area. Fundamental aspects, including perovskite nucleation and growth, heterojunction electron–hole transfer, electronic structure, and luminescence within confined spaces, are highlighted, with suggestions of approaches by which guest confinement within MOFs can be synthetically designed. We further address the underlying principles and discuss the new insights and tools for the manipulation of these composite materials for the development of synthetic microporous semiconducting composites, as well as new strategies for host–guest interfacial engineering.

“…Smart integration of MOFs with perovskites has been proven to control the agglomeration allows excellent features like high thermal stability, significant water resistance stable photoluminescence, excellent charge separation efficiency, and important gas capturing/activation ability. [ 66–73 ] Recently, a few strategies have been reported for synthesizing hybrid MOFs by encapsulating various perovskite halides (hybrids denoted as MHP@MOF), allowing optoelectronic and energy harvesting applications.

FETs), light-emitting diodes (LED), solar cells, water splitting, and water purification owing to their exceptional electronic and optical properties such as extreme absorption coefficient, robust photoluminescence, extended carrier diffusion length, ambipolar charge transport, defect tolerant nature, and similar effective mass value. [1-9] Mitzi et al. reported tin-based perovskites as a new family of semiconductors in 1994. [10] However, real attention was captured only in 2009, when Kojima et al. successfully used them in solar cells as a sensitizer in a dye-sensitized solar cell (DSSC) with the power conversion efficiency (PCE) of 3.8%. [11] Recently, other groups demonstrated halide perovskites as solid-state PSCs with 10% efficiency, which provided considerable impetus for the field, together with the recent spectacular rise in PCE (25.2% certified). [12,13] Apart from solar cells, perovskite halides have been successfully implemented in optoelectronic devices such as FETs and LEDs. [14-17] However, the structural features of perovskites experience swift degradation under different stress conditions such as moisture, UV light, oxygen, and high temperature, which limits their practical applications. [18] This drawback can be tackled by stabilizing halide perovskites by various approaches such as integration of multiple capping agents/stabilizers and encapsulation into various porous materials like polymer matrices, polymethyl Metal halide perovskites (MHPs) have excellent optoelectronic and photovoltaic applications because of their cost-effectiveness, tunable emission, high photoluminescence quantum yields, and excellent charge carrier properties. However, the potential applications of the entire MHP family are facing a major challenge arising from its weak resistance to moisture, polar solvents, temperature, and light exposure. A viable strategy to enhance the stability of MHPs could lie in their incorporation into a porous template. Metal-organic frameworks (MOFs) have outstanding properties, with a unique network of ordered/functional pores, which render them promising for functioning as such a template, accommodating a wide range of MHPs to the nanosized region, alongside minimizing particle aggregation and enhancing the stability of the entrapped species. This review highlights recent advances in design strategies, synthesis, characterization, and properties of various hybrids of MOFs with MHPs. Particular attention is paid to a critical review of the emergence of MHP@MOF for comprehensive studies of next-generation materials for various technological applications including sensors, photocatalysis, encryption/decryption, light-emitting diodes, and solar cells. Finally, by summarizing the state-of-the-art, some promising future applications of reported hybrids are proposed. Considering the inherent correlation and synergic functionalities of MHPs and MOFs, further advancement; new functional materials; and applications can be achieved through designing MHP@MOF hybrids.
