Multicomponent polymerizations (MCPs) provide a powerful synthetic tool for the construction of polymers with complex structures and multifunctionalities, owing to their great structural diversity, mild condition, high efficiency, simple procedure, and environmental benefit. They possess significant advantages in synthesizing heteroatom-rich or heterocycle-containing functional polymers through directly constructing fused heterocycles from the MCP. In this work, the MCPs of diynes, disulfonyl azides, and 2-hydroxybenzonitrile or 2-aminobenzonitrile were reported under the catalysis of CuCl and Et3N, generating iminocoumarin/quinoline-containing poly(N-sulfonylimine)s with high molecular weights (up to 37700 g/mol) and high yields (up to 96%). The MCPs enjoy a wide monomer scope and high atom economy, releasing N-2 as the only byproduct. The fluorescent poly(N-sulfonylimine) can be utilized for sensitive and selective detection of Ru3+, which also possesses antibacterial properties. The efficient MCPs could produce polymers with unique structures and functionalities, thereby accelerating the development of polymer materials.
