摘要:
A series of novel lanthanide coordination polymers (Ln-CPs) have been constructed by 2-(pyridin-2-yl-N-oxide)-1H-imidazole-4,5-dicarboxylate (H3POIDC) ligand, which derived from the partial oxidation of 2-(pyridin-2-yl)-1H-imidazole-4,5-dicarboxylate (H3PIDC) in situ reaction. Compounds 1-3 with the infinite left-and right-hand helices show 3D supramolecular structure constructing from 1D chains connecting each other through strong hydrogen-bond interactions. Compounds 4-7 show 2D layered structure with sql topology which are built from 4-connected nodes. Moreover, compounds 1-6 show strong luminescence emission in solid state, especially compound 1 exhibits obvious luminescence quenching for Hg2+ ion. (C) 2015 Elsevier B.V. All rights reserved.
