Photosensitive antibacterial modified porphyrin metal organic framework material and preparation method thereof

The invention relates to a photosensitive antibacterial modified porphyrin metal organic framework material and a preparation method thereof, and belongs to the technical field of antibacterial materials. The preparation method comprises the following steps: firstly, carrying out carboxyl activation on a porphyrin metal organic framework material with photosensitive activity by utilizing a carbodiimide method; and then, carrying out amide condensation on a targeting ligand with amino with the activated porphyrin metal organic framework material, so that the functionalized nano-antibacterial material with the morphology and the crystal structure not affected is obtained, and the material has the enhanced bactericidal performance on bacteria. The photosensitive antibacterial material with targeting ligand modification can target specific infectious bacteria, has better bactericidal performance, and has a very good application prospect. 本发明涉及一种光敏抗菌的改性卟啉金属有机骨架材料及其制备方法，属于抗菌材料技术领域。本发明利用碳二亚胺法，将具有光敏活性的卟啉金属有机骨架材料先进行羧基
