A novel metal-organic framework material, Bi-TCPP, was synthesized by a convenient one-step hydrothermal method. Bi-TCPP exhibits ultrafast singlet oxygen generation ability and a high photothermal conversion efficiency. It also demonstrates excellent antibacterial and repair effects, suggesting its potential application in the field of biomedicine.
Bismuth metal-organic frameworks (MOFs) as catalysts are scarce. Herein, the first MOF comprising meso- tetra(4-carboxyphenyl) porphine (TCPP) as an organic ligand and Bi ion as a metal node, denoted as Bi-TCPP, is synthesized by a convenient one-step hydrothermal method. Compared to other 2D (Cu-TCPP) or 3D (PCN-222) MOFs with TCPP as a ligand, Bi-TCPP has ultrafast singlet oxygen generation ability and a high photothermal conversion efficiency of 49.5% under the irradiation of 660 nm light. This is due to Bi-TCPP's strong ligand-to-metal charge transfer (LMCT) events that form singlet oxygen (O-1(2)). Further, when the electrons and holes above the bandgap relax to the band edge, the excess energy is converted into heat. In vitro and in vivo experiments show excellent antibacterial and repair effects. Hence, the synthesis of Bi-TCPP provides new ideas for the study of rare bismuth-based MOFs, and its excellent biocompatibility provides a possibility for further application.
