In recent years

porous organic polymers (POPs) have become a hot topic and developed rapidly owing to their wide application potentials in gas storage and separation

heterogeneous catalysis

and optical application. These materials possess high specific surface area and permanent porosity

and reveal advantages of high chemical and thermal stability

low density

abundant available monomers

and well established synthesis approaches. Post-modification on the established porous networks is a good strategy to modulate their porosities and skeleton structures to achieve the new functionalized materials. In this review

the state-of-the-art studies of different class of POPs as functional platforms are introduced at first

and the recent progress in the post-modification strategy is highlighted afterwards

then some outlooks on frontiers of functional exploration and potential applications is put forward at the end of this paper.
