Abstract
Porous organic polymers (POPs) feature high surface areas, tunable components, and designable hierarchical pores, thus showing versatile applications including catalysis, separation, gas storage and so on. However, the inherently hydrophobic property may be unfavorable for the catalytic reaction that involves hydrophilic reactants. By using the hydrophilic principle of the amide bond, R-NH-CO-R can be constructed in the porous frameworks to regulate the wettability. Herein, we report the construction of an amphiphilic and hierarchical porous Mn-N4 catalyst via the solvothermal copolymerization, in which N,N-methylenebisacrylamide is used as a hydrophilic monomer. This POP-based manganese catalyst can effectively promote the oxidation of secondary alcohol to produce the ketone using aqueous hydrogen peroxide as the oxidant under mild conditions. Note that this amphiphilic catalyst displays high catalytic activity as its homogeneous counterpart in the selective oxidation of alcohols. The present work has provided a successful approach for improving the catalytic activity by tuning the wettability of POP-based heterogeneous catalysts. (c) 2022 Elsevier Inc. All rights reserved.
