X‐yne click polymerization

Alkyne-based click polymerizations have been nurtured into a powerful synthetic technique for the preparation of new polymers with advanced structures and versatile properties. Among them, emerging thiol-yne, hydroxyl-yne, amino-yne made remarkable progress from reactions to applications. These avoid usage inherently dangerous monomers are safer operate than classical azide-alkyne polymerization (AACP), making them more prospective diverse To greatly promote alkyne-based beyond AACP, concept “X-yne polymerization” is proposed unify where “X” denotes that can react alkynes under mild reaction conditions, including thiols, alcohols, amines, other promising ones. In this review, we mainly present brief account X-yne discuss in detail challenges opportunities field.
