Valorization of Click-Based Microporous Organic Polymer: Generation of Mesoionic Carbene–Rh Species for the Stereoselective Synthesis of Poly(arylacetylene)s

This work reports the functionalization of azide–alkyne click-based microporous organic polymer (CMOP). The generation of triazolium salts and successive deprotonation induced mesoionic carbene species in hollow CMOP (H-CMOP). Rh­(I) species could be coordinated to the mesoionic carbene species to form H-CMOP-Rh, showing excellent heterogeneous catalytic performance in the stereoselective polymerization of arylacetylenes.
