文摘

Robust catechol-functionalized porous organic polymers (POPs) with tunable porosities (560鈥?050 m²/g) and degrees of functionalization were synthesized using a cobalt-catalyzed 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.
