“…Meanwhile,t he three white-light-emitting perovskites with higher PLQYs than our MOFs show as ignificant decrease in emission intensity after 24-72 hi rradiation under the same conditions (Figure S19). [7,11,40] Second, the functionalization of TMOF-5 is achieved by isoreticular synthesis employing 2-aminoterephthalic acid (NH 2 -bdc);t he resulting amino-functionalized framework is atypical precursor for postsynthetic MOF modification (Figure 1c). [23] X-ray crystallography reveals that the resultant TMOF-5(Br)-NH 2 is isostructural to the parent TMOF-5 with nearly identical unit cells but having the amino-functionalities pointing towards the porosity (Tables S3 and S5).…”

“…However, the PLQEs of these corrugated-2D hybrids are shows the maximum PLQE of 1.5%. The most efficient white light emitting corrugated-2D hybrid, EDBEPbBr 4 , with a CIE coordinate of (0.30, 0.42) and a correlated color temperature (CCT) of 6519 K, has a PLQE of 9% in bulk single crystal form and 18% in microscale crystal form ( Figure 6(c)) [114]. To make these phosphors practically attractive for solid-state lighting, further improving the PLQEs is required.…”

Organic-inorganic metal halide hybrids have emerged as new generation functional materials with exceptional structure and property tunability for a variety of applications. Besides the most investigated ABX 3 metal halide perovskites, a variety of hybrids consisting of a wide range of organic cations and metal halide anions have been developed and studied recently. Here, we provide an overview of these new materials possessing various crystallographic structures, including double perovskites, low dimensional hybrids, and other perovskite-related materials. We discuss their syntheses, functional properties, and optoelectronic applications. Challenges and opportunities are then laid out for these hybrid materials beyond perovskites. IMPACT STATEMENTBy choosing appropriate organic cations and metal halide anions, single crystalline ionically bonded hybrid materials can be assembled to possess various structures beyond the well-known ABX 3 perovskite. These hybrid materials exhibit exciting new properties with potential applications in a variety of areas. ARTICLE HISTORY

“…Recently, assemblies of corrugated lead halide perovskites have been reported, which exhibit photoluminescence across the entire visible spectrum upon UV excitation, with a photoluminescence quantum efficiency (PLQE) up to 9% . In the early stage, these corrugated structures of 2D perovskites were studied in the form of bulk single crystals, showing a redshifted and broad emission.…”

“…Emission‐wavelength‐dependent dynamics of the self‐trapped exciton luminescence are observed, indicative of an energy distribution of photogenerated emissive states in the perovskite . Yuan et al further improved the synthesis of these kinds of corrugated 2D perovskites by adopting a simplified polar‐solvent‐free approach with a high synthetic yield of 96% . The as‐prepared microscale perovskites showed much higher PLQE up to ≈18% and better thin‐film processability.…”

Two‐dimensional (2D) materials attract great attention due to their unique and novel properties in optics, electronics, magnetics, etc. Various 2D materials have been developed since the discovery of graphene, including hexagonal boron nitrides (h‐BNs), transition‐metal dichalcogenides (TMDs), black phosphorus, and so on. Meanwhile, metal halide perovskites are also of great interest because of their high absorbance, high quantum yield, color tunability in the visible‐light range, and high color purity with narrow full width at half maximum (FWHM). Thus, what happens if 2D materials and metal halide perovskites combine? Here work on 2D metal halide perovskites, a class of new 2D materials, is introduced. Besides the advantages of metal halide perovskites, such as high quantum yield, high color purity, and so on, 2D materials are suitable for flexible and wearable devices, giving 2D metal halide perovskites a more and more important role in energy, information displays, illumination, and many other applications.
