Construction of new zinc(II) coordination polymers by 1-(triazol-1-yl)-2,4,6-benzenetricarboxylate ligand for sensitizing lanthanide(III) ions and sensing small molecules

Two zinc(II) coordination polymers with 1-(triazol-1-yl)-2,4,6-benzenetricarboxylate ligand have been prepared under hydrothermal conditions. Notably, they perform as host for the encapsulation of Ln(III) ions and both Eu0.2Tb0.8@1 and Eu3+@2 present white-light emission. In addition, 2 exhibits highly luminescent sensing properties for acetone.334
