The Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) has recently proven to be a powerful synthetic tool in various fields of chemistry, including protein-polymer conjugation. In this article, we describe a fluorogenic CuAAC, which allows for efficient monitoring of protein-polymer conjugation. We show
