| Abstract: | A novel three-dimensional (3D) d-f heterometallic metal-organic framework (MOF) formulated as EuCd1.5L2(H2O)3] · 2H2O ( 1 ) H3L = 5-(4-(tetrazol-5-yl)phenyl)isophthalic acid] was successfully synthesized and characterized. Structural analysis displays that 1 features a 3D (3, 12)-connected framework constructed by Eu2Cd3(tetrazole)4(COO)8] units. The powder X-ray diffraction measurement of 1 immersed in different solvents reveals that 1 possess good solvent stability. It is worth noting that 1 displays highly selective detection for ronidazole (RDZ) and 4-nitrophenol (4-NP) through luminescence quenching. The possible mechanism of luminescent sensing is also well discussed. |
