Covalent organic frameworks (COFs) have attracted great attention across diverse research fields. However, only a few reports about the biomedical application of COFs are found in the literature. Attributed to the highly porous and tunable structure, as well as good thermal stability, COFs show great potential as drug carriers for chemotherapy. In this work, doxorubicin (DOX) was successfully in situ loaded into a COF by a one-pot method for the first time. The resultant DOX@COF platform exhibited high drug-loading capacity (32.1 wt %) and pH-responsive release property. In vitro and in vivo experiments demonstrated its good biocompatibility and enhanced antitumor efficacy.
