Polymer chemistry, probably more than any other chemical , relies on highly efficient organic reactions.1 Indeed, macromolecular reactions such as polymer growth (i.e., - or step-growth), polymer modification (i.e side-chains or -ends) and chain-chain coupling (i.e., block copolymer , bioconjugation) generally require high-yield and highly chemical reactions.2 In that context, it comes as no thatmodular reactions of the “click”-type3 have recently gaining popularity in polymer science. For instance, more 300 articles, describing the relevance of copper-catalyzed /alkyne cycloadditions (CuAAC) in polymer synthesis, have published within the last five years.4 These archetypal “click” reactions open multiple possibilities in terms of macromolecular .
