An unprecedented mode of reactivity of Zn 4 O‐based metal–organic frameworks (MOFs) offers a straightforward and powerful approach to polymer‐hybridized porous solids. The concept is illustrated with the production of MOF‐5‐polystyrene wherein polystyrene is grafted and uniformly distributed throughout MOF‐5 crystals after heating in pure styrene for 4–24 h. The surface area and polystyrene content of the material can be fine‐tuned by controlling the duration of heating styrene in the presence of MOF‐5. Polystyrene grafting significantly alters the physical and chemical properties of pristine MOF‐5, which is evident from the unique guest adsorption properties (solvatochromic dye uptake and improved CO 2 capacity) as well as the dramatically improved hydrolytic stability of composite. Based on the fact that MOF‐5 is the best studied member of the structure class, and has been produced at scale by industry, these findings can be directly leveraged for a range of current applications.
