Abstract
In the current study, a novel luminescent dinuclear coordination compound was prepared by the solution method and named [Ag(aca)(μ-3,3′-abpt)]2 (I) (3, 3′-abpt = 4-amino-3,5-bis(3-pyridyl)-1,2,4-triazole and Haca = 9-anthracene carboxylic acid). Structural analysis showed that the compound has a zero-dimensional (0D) fundamental structure, comprising several intermolecular interactions resulting in a tightly packed three-dimensional (3D) framework. In addition, powder X-ray diffraction, elemental analysis, infrared (IR), and luminescence property were performed to further characterize the compound. The compound exhibited excellent stability in aqueous solution. Moreover, it showed favourable luminescence emission under ultraviolet (UV) light irradiation at room temperature. These findings show that the compound can be used as luminescent sensor for detection of Fe3+ and Cr2O72− in aqueous solution with high selectivity, sensitivity, and good anti-interference ability. The possible sensing mechanisms were also investigated. Such an effective detection method may provide inspiration for the detection of other kinds of orange-yellow substances such as dye molecules.
