Low-cost and easy-to-prepare carbon dots (CDs) are attractive quasi-homogeneous photocatalyst alternatives, but their applicability is limited by their short photoluminescence (PL) lifetimes. By tuning the surface and PL properties of CDs, we designed colloidal CD nano-photocatalysts for a broad range of Ni-mediated cross-couplings between aryl halides and nucleophiles. In particular, a CD decorated with amino groups permitted coupling to a wide range of aryl halides and thiols under mild, base-free conditions. Mechanistic studies suggested dynamic quenching of the CD excited state by the Ni co-catalyst and identified that pyridinium iodide (pyHI), a previously used additive in metallaphotocatalyzed cross-couplings, can also act as a photocatalyst in such transformations.","lang":"eng"}],"author":[{"full_name":"Zhao, Zhouxiang","first_name":"Zhouxiang","last_name":"Zhao"},{"full_name":"Pieber, Bartholomäus","first_name":"Bartholomäus","orcid":"0000-0001-8689-388X","last_name":"Pieber","id":"93e5e5b2-0da6-11ed-8a41-af589a024726"},{"first_name":"Martina","full_name":"Delbianco, Martina","last_name":"Delbianco"}],"doi":"10.1021/acscatal.2c04025","_id":"12923","publication_identifier":{"eissn":["2155-5435"]},"volume":12,"date_updated":"2023-05-15T08:30:13Z","type":"journal_article","extern":"1","date_published":"2022-10-27T00:00:00Z","article_type":"original","year":"2022","publisher":"American Chemical Society","day":"27","keyword":["Catalysis","General Chemistry"],"issue":"22","oa_version":"Published Version","main_file_link":[{"url":"https://doi.org/10.1021/acscatal.2c04025","open_access":"1"}],"title":"Modulating the surface and photophysical properties of carbon dots to access colloidal photocatalysts for cross-couplings","quality_controlled":"1","scopus_import":"1","intvolume":"        12","language":[{"iso":"eng"}]}
