A supramolecular ensemble of Cu₂O-Ag nanoparticles (NPs) and aggregates of perylene bisimide (PBI) derivative has been developed in mixed aqueous media. The as prepared supramolecular ensemble exhibits high catalytic efficiency in the one-pot, three-component click reaction for the preparation of 1,2,3-triazoles under “green” conditions (room temperature, mixed aqueous media, and recyclable catalytic system). The catalytic system also works efficiently for the synthesis of isatin and coumarin derivatives having pharmaceutical importance. Interestingly, a “dip strip”, prepared by dip coating a filter paper strip with the solution of the supramolecular ensemble, serves as an efficient heterocatalytic system for the one-pot, three-component reaction. The as prepared dip strip could be reused efficiently for the one-pot, three-component click reaction up to five cycles.

sim双酰亚胺衍生物和Cu ₂ O-Ag纳米粒子的超分子集合：室温下一锅，三组分点击反应的纳米/“浸渍条”催化体系

Cu _2的超分子集合体O-Ag纳米颗粒（NPs）和per双酰亚胺（PBI）衍生物的聚集体已在混合水性介质中开发出来。所制备的超分子整体在“绿色”条件（室温，混合水介质和可循环使用的催化体系）下，在制备1,2,3-三唑的单锅，三组分点击反应中显示出高催化效率。该催化体系还有效地用于合成具有药物重要性的靛红和香豆素衍生物。有趣的是，通过用超分子集合体溶液浸涂滤纸带而制备的“浸涂带”可作为一种高效的杂化催化体系，用于一锅，三组分反应。所准备的浸渍条可有效地重复使用至一锅，三组分点击反应（最多五个循环）。
