Recent Advances in Alkyne‐Based Multicomponent Polymerizations

Multicomponent polymerization (MCP) is an emerging field of polymer chemistry, which inherits a series of advantages from multicomponent reactions (MCRs), such as high efficiency, mild reaction condition, atom economy, and operational simplicity. Great efforts have been made to develop MCRs into MCPs, providing an easy access to a library of polymers with facilely tunable structures. However, MCPs of alkynes with large potential and wide prospects in the preparation of optoelectronic materials are still in its infancy, despite of the rich chemistry of alkynes. In this paper, the recent development of alkyne‐based MCPs is summarized. The multicomponent tandem polymerization with two or more steps combined in a one‐pot procedure is presented, providing an efficient and convenient new approach for the synthesis of conjugated polymers. The new trend of pursuing catalyst‐free “green” chemistry in MCPs is also introduced. image
