Abstract
Porous organic polymers (POPs) are of growing research interest owing to their high surface
areas, stabilities, controllable chemical configurations, and tunable pore volumes. The molecular
nanoarchitecture of POP provides metal or metal oxide binding sites, which is promising for the
development of advanced heterogeneous catalysts. This article highlights the development of
numerous kinds of POPs and key achievements to date, including their functionalization and
incorporation of nanoparticles into their framework structures, characterization methods that are
predominantly in use for POP-based materials, and their applications as catalysts in several reactions.
Scientists today are capable of preparing POP-based materials that show good selectivity, activity,
durability, and recoverability, which can help overcome many of the current environmental and
industrial problems. These POP-based materials exhibit enhanced catalytic activities for diverse
reactions, including coupling, hydrogenation, and acid catalysis.
