A facile, efficient approach for preparation of functionalized aromatic polysulfones by postpolymerization modification with thiol-ene click chemistry is described. The key synthetic strategy is to incorporate a pendant vinyl ether group into polysulfones as a reactive precursor with controlled degrees of functionalization. Synthetic utility of the pendant alkenyl group is demonstrated by generating diverse polymer derivatives using thiol-ene functionalization including glycosylated polysulfone. Finally, the highly reactive alkene platform in the polymer affords convenient, metal-free, and azide-free click transformations to create diverse ranges of new functionalized polysulfones that could be applied in various applications.
