Tóm tắt

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.
