Abstract: As an emerging new technique, chain-growth polymerization of ABm monomers using the efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction has enabled the synthesis of structurally defined hyperbranched polymers in solution. In this presentation, we demonstrate the high versatility in the monomeric design by proposing a modular AB2-R monomer structure that was composed of three structural motifs (one alkynyl group, two azido groups, and a dangling R group) connected by two space linkers (S1 and S2). The influence from the structural parameters of S1, S2, and R groups on the polymerization kinetics, the molecular weights, and the DB was systematically studied. Subsequently, we further expanded the monomer library with a series of orthogonal functionalizable monomer which enabled efficient and quantitative post-modification of hyperbranched polytriazoles. These explorations may offer new thoughts to fulfill sophisticated nanostructures and functions
