AbstractIn this work, a novel 1D metal‐mediated hydrogen‐bonded framework with rich phenyl groups is first synthesized employing Co2+ and dibenzoylmethane (DBM) as precursors, which are named HOF‐Co‐DBM and exhibit exceptional thermal stability, excellent chemical durability, and super hydrophobicity. These distinctive properties can be attributed to the high density, robust Co─O coordination bonds, and the presence of strong hydrogen bonds (O─H─O─C) characterized by short bond distances, which contribute to its close‐packed structure. Additionally, the benzene rings flanking the framework further enhance its hydrophobicity. The HOF‐Co‐DBM is subsequently integrated into a polyurethane (PU) sponge, resulting in exceptional oil removal performance. This study demonstrates the potential for preparing ultra‐stable and superhydrophobic hydrogen‐bonded organic framework materials with a wide range of applications.
