Abstract
This study reports the synthesis and characterization of a novel CsCu(2)I(3)@UiO-66(Ce)-NH(2) hybrid material through the state-of-the-art in-situ growth of the lead-free and non-toxic CsCu(2)I(3) perovskite within the porous UiO-66(Ce)-NH(2). The composite exhibits a high surface area with the CsCu(2)I(3) nanostructures uniformly dispersed within the UiO-66(Ce)-NH(2) framework. The host-guest CsCu(2)I(3)@UiO-66(Ce)-NH(2) was considered as an effective and stable catalyst for the one-pot three-component copper(I)-catalyzed intermolecular alkyne-azide cycloaddition (CuAAC) or click reaction. Under optimized conditions, utilizing water at room temperature, the nominal catalyst exhibited superior activity, outperforming its individual components. Remarkably, the CsCu(2)I(3)@UiO-66(Ce)-NH(2) catalyst demonstrated good recyclability and reusability over several catalytic runs. Mechanistic studies unveiled a synergistic cooperation between the CsCu(2)I(3) and MOF, leading to the enhanced catalytic performance and improved stability of the perovskite. The developed multifunctional porous solid offers potential applications in catalysis and related fields, paving the way for innovative and sustainable organic synthesis and beyond.
