Although C–H functionalization is one of the simplest reactions, it requires use highly active and selective catalysts. Recently, C–H-active transformations using porous materials such as crystalline metal-organic frameworks (MOFs) covalent-organic (COFs) well amorphous porous-organic polymers (POPs) new emerging heterogeneous catalysts have attracted significant attention due to their promising activity potential material tunability. These solids offer exceptional structural uniformity, facile tunability permanent porosity. In addition, tuning catalytic selectivity these can be achieved through engineering site microenvironments, metal node substitution, linker changes, node/linker functionalization, pore modification. The present review provides an overview current state art on MOFs, COFs POPs advanced for various bond activation providing details about chemo-, regio-, stereo-selectivity control, comparing performance with that other catalysts, triggering additional research by showing limitations challenges in this area, a perspective future developments.
