Abstract
AbstractPorous metal–organic framework (MOF) liquids with permanent porosity, good fluidity, and fine dispersion attract broad attention in catalysis, transportation, gas storage, and chemical separations. Yet, the design and synthesis of porous MOF liquids for drug delivery remain less explored. Herein, a simple and general strategy is reported to prepare ZIF‐91 porous liquid (ZIF‐91‐PL) via surface modification and ion exchange. The cationic nature of ZIF‐91‐PL not only renders it antibacterial but also with high curcumin loading capacity and sustained release. More importantly, the acrylate group on the grafted side chain of ZIF‐91‐PL makes it feasible to crosslink with modified gelatin through light curing, and the obtained hydrogel shows a significantly improved healing effect on the wound of diabetes. This work demonstrates for the first time, a MOF‐based porous liquid for drug delivery, and the further fabrication of composite hydrogel may have potential applications in biomedical science.
