Selective Adsorption of Dyes and Fe Sensing via Tb Incorporation in an Anionic Cadmium-Organic Framework.

A three-dimensional (3D) anionic cadmium-organic framework, namely [(CH)NH][Cd(DMTDC)] ⋅ 2DMA ⋅ 0.5HO (Cd-MOF; DMA=N,N-dimethylacetamide), was successfully synthesized under solvothermal conditions by using a linear thienothiophene-containing dicarboxylate ligand, 3,4-dimethylthieno [2,3-b]-thiophene-2,5-dicar-boxylic acid (HDMTDC). Single-crystal X-ray diffraction analysis reveals that Cd-MOF exhibits a 3D anionic framework with pcu α-Po topology, featuring rectangle and rhombus-shaped channels along b- and c- axis direction.

Highly selective luminescence sensing for Cu2+ ions and selective CO2 capture in a doubly interpenetrated MOF with Lewis basic pyridyl sites.

A doubly interpenetrated MOF was constructed using a new pyridyl carboxylate ligand with active pyridyl sites, which exhibits highly efficient luminescence sensing for Cu(2+) ions and sorption selectivities of CO2 over CH4 and N2.
