Synthesis and Metalation of Catechol-Functionalized Porous Organic Polymers

Robust catechol-functionalized porous organic polymers (POPs) with tunable porosities (560-1050 m(2)/g) and degrees of functionalization were synthesized using a cobalt-catalyzed acetylene trimerization (COAT) 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.
