Abstract

Robust catechol-functionalized porous organic polymers (POPs) with tunable porosities (560-1050 m ²/g) and degrees of functionalization were synthesized using a cobaltcatalyzed acetylene trimerization (CCAT) strategy. Post-synthesis metalation can be readily carried out with a wide range of metal precursors (Cu ^II, Mg ^II, and Mn ^II salts and complexes), resulting in metalated POPs with enhanced heat of hydrogen adsorptions compared to the starting nonmetalated materials.
