Interestingly, Cu(I) clusters can also be emissive, and the extension from small molecules to larger architecture could represent the first step towards novel materials that could be obtained by programming the units to undergo self\u2010assembly. However, for Cu(I) compounds the formation of supramolecular systems is challenging due to the coordinative diversity of copper centers. This works shows that this diversity can be exploited in the construction of responsive systems. In detail, the changes in the emissive profile of different aggregates formed in water by phosphine\u2010thioether copper(I) derivatives were followed. Our results demonstrate that the self\u2010assembly and disassembly of Cu(I)\u2010based coordination polymeric nanoparticles (CPNs) is sensitive to solvent composition. The solvent\u2010induced changes are related to modifications in the coordination sphere of copper at the molecular level, which alters not only the emission profile but also the morphology of the aggregates. Our findings are expected to inspire the construction of smart supramolecular systems based on dynamic coordinative metal centers.<\/jats:p>","DOI":"10.1002\/chem.202100865","type":"journal-article","created":{"date-parts":[[2021,4,26]],"date-time":"2021-04-26T02:55:55Z","timestamp":1619405755000},"page":"8308-8314","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Self\u2010Assembly and Aggregation\u2010Induced Emission in Aqueous Media of Responsive Luminescent Copper(I) Coordination Polymer Nanoparticles"],"prefix":"10.1002","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6068-4438","authenticated-orcid":false,"given":"Hugo","family":"Hern\u00e1ndez\u2010Toledo","sequence":"first","affiliation":[{"name":"Facultad de Qu\u00edmica Universidad Nacional Aut\u00f3noma de M\u00e9xico Ciudad Universitaria  04510 Cd.
