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

A series of heterometallic cluster organic frameworks based on cuprous-halide Cu 4 I 4 clusters and lanthanide clusters, [Ln 2 (H 2 O) 8 ] 2 (Cu 4 I 4 )(pdc) 4 ][NO 3 ] 4 ·solvent ( 1 -Ln , Ln = Y, Tb, Eu, H 2 pdc = 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 Cr 2 O 7 2− from aqueous solution. Additionally, the luminescence properties of 1 -Tb and 1 -Eu have also been investigated.
