Present and Perspectives of Photoactive Porous Composites Based on Semiconductor Nanocrystals and Metal-Organic Frameworks

Abstract

This review focuses on the recent developments in synthesis, properties, and applications of a relatively new family of photoactive porous composites, integrated by metal halide perovskite (MHP) nanocrystals and metal-organic frameworks (MOFs). The synergy between the two systems has led to materials (MHP@MOF composites) with new functionalities along with improved properties and phase stability, thus broadening their applications in multiple areas of research such as sensing, light-harvesting solar cells, light-emitting device technology, encryption, and photocatalysis. The state of the art, recent progress, and most promising routes for future research on these photoactive porous composites are presented in the end.

The Materials and Application of Artificial Light Harvesting System Based on Supramolecular Self‐assembly

“…The shortcomings of the above synthetic methods (difficult synthesis and separation, high environmental requirements) can be solved by effective molecular design and functionalized assembly in artificially simulated light-harvesting systems. So far, the light-harvesting systems based on supramolecular assemblies mainly include several categories: macrocyclic compounds, vesicles, [15][16][17][18] proteins [19][20][21][22] and organic nanomaterials, [23][24][25] organogel materials, organic-inorganic hybrids, liquid crystal materials, and so on.…”

Binding of CsPbBr3 Nanocrystals to MOF-5 for the Detection of Cadmium Ions in Aqueous Media

“…20,21 Nanocrystals when incorporated into MOFs have previously shown novel synergistic properties that are much superior to those offered by any other encapsulants. 22 For instance, the chemical stability of CNCs has enhanced polar solvents when formed into their MOF composites as CsPbBr 3 @AMOF-1. 17, 23 Similarly, photoluminescence (PL) of the CsPbBr 3 @Uio-67 composite was stable up to 30 days under ambient conditions, which is unlikely in pristine CsPbBr 3 crystals.…”

PdS Quantum Dots as a Hole Attractor Encapsulated into the MOF@Cd0.5Zn0.5S Heterostructure for Boosting Photocatalytic Hydrogen Evolution under Visible Light

“…Common QDs include perovskite, carbon, and metal sulfide. Perovskite QDs are promising materials in many fields such as photocatalysis and optoelectronic applications due to their excellent properties, such as high absorption coefficient, low composite loss, high defect tolerance, low-cost processing, long charge diffusion length, and easy band gap adjustment. , Carbon QDs mainly include graphene, nanodiamond, carbon nitride, and so forth. They have excellent properties comparable to traditional semiconductor QDs and can effectively overcome the defects of high toxicity and poor biocompatibility.…”
