N2 - Through a dual-ligand strategy, two Zn(II) coordination polymers (CPs) including [Zn(L)(phen)]·0.5DMF (1) and [Zn2(L)2(4,4′-bipy)]·4DMF (2) have been synthesized from a sulfone-functionalized dicarboxylate (H2L = 2,2′-sulfone-4,4′-dicarboxylic acid) with the help of different N-donor co-ligands (phen = 1,10-phenanthroline, 4,4′-bipy = 4,4′-bipyridine). X-ray diffraction analyses reveal that the final structures are deeply influenced by the co-ligands. With chelate phen as the co-ligand, a double linear chain (1) is obtained. However, a 3D layer-pillared network (2) is generated with 4,4′-bipy as the co-ligand. Luminescence studies reveal that 1 and 2 show strong fluorescence in DMF, and they can serve as promising sensors for detection of trace amounts of nitrofurantoin (NFT) and nitrofurazone (NFZ) antibiotics via luminescence quenching. The KSV values of 1 and 2 are 1.45 × 104 M−1 and 1.30 × 104 M−1 for NFZ, and 1.27 × 104 M−1 and 1.14 × 104 M−1 for NFT, respectively. Additionally, the possible mechanism for the luminescence quenching has been investigated.
