摘要

Bi-III-MOFs 1-4 were prepared via solvothermal method using four organic linkers; 2-mercapto-3-methyl-4-thiazoleacetic acid (H(2)MMTA), 2,6-naphthalenedicarboxylic acid (2,6-NDA), 4,6-dihydroxy-2-mercaptopyrimidine (H2DMP), and 4-mercaptobenzoic acid (H(2)MBA), respectively. The resulting MOFs were structurally/morphologically characterized by UV/Vis, AAS/ICP-MS, Fourier transform infrared spectroscopy (FT-IR), H-1 NMR, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and powder X-ray diffraction technique. All these MOFs showed good luminescence properties exhibiting blue luminescence. N-2 gas adsorption isotherms of 1-4 confirmed the porosity of these frameworks. In order to evaluate the effect of metal ion upon chelation, the free organic linkers and respective MOFs were screened for their antibacterial potential against some pathogenic bacteria and appreciable activity was observed.
