Dynamic covalent polymers generated from <scp>X</scp>‐yne click polymerization

Abstract Dynamic covalent polymers have gained more and attention for their fascinating dynamic features broad application prospects. As an emerging powerful synthetic tool, X‐yne click polymerization, mainly including thiol‐yne, amino‐yne hydroxyl‐yne polymerizations, has been rapidly developed widely applied in the preparation of functional recent years. Moreover, exchange processes successively observed different adducts, then several obtained by polymerization. The combination these two aspects not only provides a highly efficient approach polymers, but also further expands scope achieving win–win situation. In this review, we sort out mechanisms based on formation β ‐heteroatom enolate intermediates give detailed account progress generated from polymerization applications adaptable networks (CANs), self‐healing injectable polymer hydrogels porous polymeric films, etc. existing deficiencies future prospects field are discussed.
