In collaboration with the group of Prof. Martín Fañanás, we have reported the red-light-driven C(sp2)–H sulfonylation of anilines using a highly stable benzothiadiazole-based covalent organic framework as an efficient, recyclable photocatalyst. Read the article in JACS, the press release and article in GCiencia. Congrats to Paula, Pedro, and all the co-authors!
