Abstract

The organic ligands (E)-8-hydroxyquinoline-2-carbaldehyde oxime (H2L1) and furan-2-ylmethanamine (H2L2) were used to react with Zn(NO3)2·6H2O at 140 °C solvothermal for two days to obtain the heptanuclear Zn(II) cluster [Zn7(L1)4(HL1)2(H2L2)(µ2-OH)(µ2-O)(NO3)] (1). The X-ray single crystal diffraction reveals that every five-coordinated Zn(II) ions are surrounded by two N atoms and three O atoms with the N2O3 coordination environment and four-coordinated Zn(II) ion surrounded by one N atom and three O atoms in the NO3 coordinated environment. The photoluminescence of cluster 1 is obvious. Moreover, in the presence of Ag(I) ions, cluster 1 exhibits an efficient recognition ability, and it realizes the recognition of toxic metal ions. Here, we have developed cluster-based sensing materials for the efficient detection of heavy metal ions Ag(I) strategies. View Full-Text
