Two Novel Penetrating Coordination Polymers Based on Flexible S-containing dicarboxylate acid with Sensing Properties Towards Fe3+ and Cr2O72- ions

Publication date: Available online 13 February 2018 Source:Journal of Solid State Chemistry Author(s): Zhiwei Chen, Xiuna Mi, Suna Wang, Jing Lu, Yunwu Li, Dacheng Li, Jianmin Dou Two new coordination polymers (CPs), namely, {[Zn(L)(bpp)]∙DMF}n (1) and {[Zn(L)(bpe)]∙DMF}n (2) (L = 2,2'-[benzene-1,3-diylbis(methanediylsulfanediyl)]dibenzoic acid, bpp= 1,3-bis(4-pyridyl)propane, bpe = 1,2-Bis(4-pyridyl)ethylene, DMF = N,N-Dimethylformamide), have been solvothermally synthesized and fully characterized. Complex 1 displays a 2D→2D three-fold“false” interpenetrating structure while complex 2 possesses a novel 3-D 4-connected structure with fascinating self-penetrating moieties. The luminescence studies reveal that these complexes exhibited excellent selectivity for Fe3+ and Cr2O7 2- ions in DMF. The sensing mechanism was investigated through PXRD, XPS , EDS mapping measurements, and discussed in details. Graphical abstract
