Abstract Hydrogen‐bonded organic frameworks (HOFs) have shown promise in various fields; however, the construction of HOF/polymer hybrid membranes that can maintain both structural and functional integrity remains challenging. In this study, we here fabricated a new HOF ( HOF‐50 ) with reserved polymerizable allyl group via charge‐assisted H‐bonds between carboxylate anion amidinium, subsequently copolymerized monomers to construct covalently bonded (polyHOF) membrane. The resulting polyHOF membrane not only exhibits customizable mechanical properties extreme stability, but also shows an exceptional ratiometric luminescent temperature‐sensing function very high sensitivity visibility even when lanthanide content is two orders magnitude lower than reported mixed‐lanthanide metal–organic (MOFs) lanthanide‐doped covalent (COFs). This orthogonal postsynthesis copolymerization strategy may provide general approach for preparing connected diverse applications.
