  • Two 3D microporous zinc metal-organic frameworks, formulated as [Zn3(DBA)(OH)(1, 10-phen)2]n (1) and {[Zn2(HDBA)(4, 4′-bipy)1.5]·H2O}n (2) (H5DBA=(3, 5-di(2′, 4′-dicarboxylphenyl)benzoic acid; 1, 10- phen=1, 10-phenan- throline; 4, 4′-bipy=4, 4′ -bipyridine), were synthesized under solvothermal conditions. Structural analysis shows that 1 could be described as a 3D microporous framework based on the trinuclear metal units, while 2 exhibits the micro- porous structure from the binuclear zinc groups. Compared with 2, 1 demonstrated a strong luminescence in the water, so it could be used as luminescent sensors for detection of Fe3+, Cr2O72-, and acetone molecules with high selectivity and sensitivity.
