摘要
Summary of main observation and conclusion Multicomponent polymerization(MCP)is a popular tool to construct polymers with diverse structure,simple operation,and high efficiency,which faces the challenges of limited product structures.Multicomponent tandem polymerization(MCTP),combining two or multiple reactions in a one-pot fashion,could expand the scope of MCP and enrich the polymer structures.Herein,a one-pot three-component tandem polymerization of diynes,carbonyl chloride,and Fischer's base has been developed to afford conjugated poly(diene merocyanine)s with mild condition,satisfactory molecular weights(Mw up to 10900 g/mol)and yields(up to 81%).The polymers enjoy good solubility and high thermal stability.The unique emission behavior of the model compound and polymer show that they are aggregation-induced emission(AIE)-active,suggesting that the diene merocyanine moiety is a potential AIEgen.This MCTP shows great potential in the preparation of functional polymer materials,which could build new AlE functional units directly from the polymerization,demonstrating its synthetic simplicity and elegance.
