Abstract: Three metal organic frameworks (MOFs), UiO-66, UiO-66-NH2 and UiO-66-COOH, were synthesized with different organic ligands centered on metal Zr ions,then the bendamustine was loaded into them by impregnation method, and their loading capacities were investigated in this study. Infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis, X-ray diffraction method and scanning electron microscope were used to characterize the MOFs before and after drug loading. The results showed that the three MOFs were successfully loaded with bendamustine and the crystal structures of them were not changed before and after drug loading. The thermal stability was strong and the drug-loading capacity of UiO-66-COOH was better than that of UiO-66-NH2 and UiO-66. According to the specific functional group of the drug, the corresponding MOFs with high matching degree can be synthesized to increase the drug loading.
