A phenanthroline-based porous organic polymer for the iridium-catalyzed hydrogenation of carbon dioxide to formate

A novel phenanthroline-functionalized porous organic polymer (phen-POP) has been designed, and prepared for the first time without other reactive functional groups in the polymer skeleton. Post-synthetic metalation of phen-POP with IrCl₃ afforded a single-site, highly active and selective catalyst for the hydrogenation of CO₂ to formate.
