Metal nanoparticles embedded in AIEE active supramolecular assemblies: robust, green and reusable nanocatalysts

Abstract

Multi-functional AIEE-active supramolecular assemblies act as nanoreactors for the preparation of different types of metal NPs. The in situ generated metal NPs stabilized by supramolecular assemblies act as nanocatalysts for various organic transformations under thermal/visible light irradiation.

Recent advances in nanoparticles towards sustainability and their application in organic transformations in aqueous media

“…26 Recently, efforts have been made to replace toxic reducing agents with environmentally benign ones, which can function both as reducing agents and stabilizers. 27 The selection of stabilizers is also important to prevent the self-agglomeration of metal NPs as the low stability and self-agglomeration of metal nanoparticles decrease the catalytic activity and recyclability of the catalytic system. Table 1 summarizes various metal NPs for organic transformation in aqueous media.…”

Cobalt-Centered Supramolecular Nanoensemble for Regulated Aerobic Oxidation of Alcohols and “One-Pot” Synthesis of Quinazolin-4(3H)-ones

“…Our research work involves the development of photocatalytic ensembles consisting of supramolecular photosensitizing host assemblies as light-harvesting antenna/stabilizers and catalytically active metallic species to perform organic transformations under green conditions. 16 Very recently, we reported supramolecular catalytic ensemble PPA@Pd which showed high efficiency in C−C bond formation. 17 In continuation of this work, we were then interested in the development of a cobalt-centered supramolecular photocatalytic ensemble for regulated aerobic oxidation of alcohols under mild reaction conditions.…”
