A multifunctional lanthanide metal–organic framework supported by Keggin type polyoxometalates

Abstract

A neodymium metal–organic framework with 1D nanotubular channels incorporating Keggin type [SiW^V₃W^VI₉O₃₈]³⁻ has been synthesized by utilizing pyridine-2,5-dicarboxylic acid as an organic ligand. It represents an unusual polyoxometalate-templated framework with the multifunctionality of magnetism, near-infrared luminescence and the selective adsorption of Rhodamine B dye molecules.
