摘要：

Due to their striking optical properties, luminescent coordination polymers as sensors for the detection of hazardous species have drawn interest of researchers in consideration of the control of environmental pollution. In this work, the organic ligand 2-(4-((E)-2-(pyridine-2-yl)vinyl)styryl)pyridine (2-bpeb), which possesses a large pi-conjugated system, was employed to react with d(10) metal ions to obtain novel luminescent coordination polymers. Three complexes [Cd(2-bpeb)(0.5)(CNA)(H2O)] (CP1), [Cd(2-bpeb)(0.5)(NDC)] (CP2) and [Zn(2-bpeb)(BDC)] (CP3) were synthesized successfully by introducing carboxylic acids of 4-carboxycinnamic acid (H(2)CNA), 2,6-naphthalene dicarboxylic acid (H2NDC) and 1,4-benzenedicarboxylic acid (H2BDC) as auxiliary ligands. Because of the existence of the large pi-conjugated system and d(10) metal ions, all of these coordination polymers exhibit striking fluorescence properties. Impressively, all of them can function as sensors for the detection of highly oxidizing anions MnO4- and Cr2O72-, with an increased sensitivity for MnO4-.
