Incorporating cuprous-halide clusters and lanthanide clusters to construct Heterometallic cluster organic frameworks with luminescence and gas adsorption properties

Abstract

A series of heterometallic cluster organic frameworks based on cuprous-halide Cu4I4 clusters and lanthanide clusters, [Ln2(H2O)8]2(Cu4I4)(pdc)4][NO3]4·solvent (1-Ln, Ln = Y, Tb, Eu, H2pdc = 3,5-pyridinedicarboxylic acid), have been successfully synthesized under solvothermal conditions. Single-crystal X-ray diffraction analysis reveals that 1-Ln show fascinating three-dimensional porous framework structures constructed from two dissimilar types of nanosized coordination cages. Gas sorption measurements indicate that 1-Ln show moderate gas uptake capacities. The UV/vis spectroscopy measurements reveal that 1-Ln are a class of potential materials for the removal of Cr2O72− from aqueous solution. Additionally, the luminescence properties of 1-Tb and 1-Eu have also been investigated.
