Conjugated porous polymers bearing flavone moieties (FL-CPPs) were synthesized a tandem approach. The carbonylative Sonogashira coupling in tandem with cyclization guided the assembling of building blocks with the accompanied production of flavone skeletons. The FL-CPPs were proved to be efficient metal-free photocatalysts for the [3+2] cycloaddition of phenols with olefins under the irradiation of visible-light.
