摘要

Two new Zn(ii) coordination complexes, formulated as [Zn(opda)(pbib)] (1) and [Zn(ppda)(pbib)(H2O)] (2), (H(2)opda = 1,2-phenylenediacetic acid, H(2)ppda = 1,4-phenylene-diacetic acid, pbib = 1,4-bis(1-imidazoly)benzene), have been synthesized. The opda ligands extend a 1D chain containing (Zn-pbib) polymer chains into a 2D layer in 1. In 2, the ppda ligands link Zn(ii) atoms to form a 2D network, then the rigid bis(imidazole) ligands give rise to the 3D structure. The fluorescence property application and mechanisms of two complexes for detecting Cr2O72- and o-NP have been researched. For two complexes, the high quenching percentage in low concentration aqueous solution are 95.75% (Cr2O72-, 1), 95.28% (Cr2O72-, 2) and 97.56% (o-NP, 1), 96.59% (o-NP, 2). Compared with 2, complex 1 has higher quenching percentage, this could be because 1 is a 3D supramolecular with a large hole. The detection limits have been measured to be 2.992 x 10(-7) M (Cr2O72-, 1), and 4.372 x 10(-7) M (Cr2O72-, 2), 2.103 x 10(-7) M (o-NP, 1), 1.862 x 10(-7) M (o-NP, 2), respectively. The emissions of two complexes could be effectively and selectively quenched by o-NP and Cr2O72-, showing their potential as multi-responsive luminescent sensors.
