Bromoacetyl Bromide-Derived CsPbBr Quantum Dots: Robust Water Stability for Aqueous-Phase Photocatalysis.

Cesium lead bromide (CsPbBr) perovskites are promising photocatalysts for organic transformations, offering a cost-effective and recyclable alternative to conventional catalysts. However, their scope is limited to nonpolar solvents due to instability in aqueous environments. Here, bromoacetyl bromide (BABr) as a novel precursor for the one-step synthesis of highly water stable, size-controlled CsPbBr quantum dots (QDs), is introduced.

Multifunctional Catalysis by a One-Dimensional Copper(II) Metal Organic Framework Containing Pre-existing Coordinatively Unsaturated Sites: Intermolecular C-N, C-O, and C-S Cross-Coupling; Stereoselective Intramolecular C-N Coupling; and Aziridination Reactions.

The coordinatively unsaturated sites () are vital in metal-centered catalysis. Metal-organic frameworks (MOFs) provide a unique opportunity to generate and stabilize due to their robust structure. Generally, the generation of in MOFs needs prior activation under heat and high vacuum to remove labile molecules occupying the catalytic sites.

Stable lead-halide perovskite quantum dots as efficient visible light photocatalysts for organic transformations.

Lead halide perovskite (LHP) based colloidal quantum dots (CQDs) have tremendous potential for photocatalysis due to their exceptional optical properties. However, their applicability in catalysis is restricted due to poor chemical stability and low recyclability. We report halide-passivated, monodisperse CsPbBrCQDs as a stable and efficient visible-light photocatalyst for organic transformations.
