A highly efficient and multicomponent step-growth polymerization via carbene intermediates is established by bimetallic relay catalytic systems. This strategy, which provides a facile synthetic pathway to novel luminescent polysulfonamides, could overcome the limitation on the choice of carbene monomers and their difficulty in achieving high-molecular-weight polymers. The polymerizations occur through a tandem Cu(I)-catalyzed click reaction and an Rh(II)-catalyzed carbene 1,3-insertion reaction. The high reactivity of Rh(II)-bonded imino carbene intermediates allows a wide range of reactivity with various carboxylic acids, alcohols, and phenols. These results point to an untapped pathway for the use of metal carbene intermediates to construct new macromolecules.
