Abstract
Two new water-stable zinc metal−organic frameworks (Zn-MOFs) formulated as [Zn(L1)(1,4-NDC)]n (1) and [Zn(L2)0.5(1,4-NDC)]n (2) (L1 = 1,4-bis(5,6-dimethylbenzimidazol-1-yl)-2-butylene, L2 = 1,4-bis(benzimidazol-1-yl)-2-butylene, 1,4-H2NDC = 1,4-naphthalenedicarboxylic acid) were synthesized and characterized. 1 possesses an unusual 3D (3,4)-connected dmc topology and 2 exhibits a rarely 2-fold interpenetrating 3D (4,5)-connected xah framework. 1 and 2 can be used as dual luminescence probes for detection of glyoxal and Cr2O72− anions in water, showing high sensitivity, selectivity and recyclability. The mechanism of the sensing glyoxal and Cr2O72− is also presented. The fluorosensors based on MOF materials for effectively sensing glyoxal have been first demonstrated.
