Porous organic polymers are porous materials that interlinked with building blocks by strong covalent bonds. The functional groups on the can be carefully chosen to obtain a POP desired functionalities. In certain cases, pores or voids interact molecules via non-covalent interactions and hence they serve as catalytic centers. many pristine POPs themselves were evaluated heterogeneous catalysts for their activity. inner of act ligand metal ions/metal nanoparticles wide range metal-ion-anchored nanoparticle-loaded reported. These catalyze different reactions metal-based catalysis following pathway. this type catalysis, plays an important role, i. e., it serves carbon matrix, interacts interactions, further in metal/metal-ion-anchored POPs, concentration is highly reduced transformation effectively takes place at interface metal/carbon matrix. Herein, we discuss recent developments metal-ion/metal nanoparticle loaded role various transformations such C-C coupling reactions, borrowing hydrogen CO2 transformations, hydroformylations oxidation alkynes 1,2-diketones C-H arylation reactions.
