Here we reported a versatile and multicomponent polymerization (MCP) approach that enabled the synthesis of functional poly(propargyl imine)s with well-defined structures and high molecular weight (M-w up to 38 200) in excellent yields (up to 93%) from readily accessible monomers of dibromoarenes, isonitriles, and diynes. This MCP had the advantages of simple operation, wide substrate scope, and mild reaction conditions. The resulting polymers possessed good solubility and showed high thermal stability and refractive indices. The tetraphenylethene-containing polymer displayed a phenomenon of aggregation-induced emission and could respond to various acidic vapors.
