Synthesis, structure and properties of a microporous Cd(II) 3,3′,4,4′-Benzophenone-tetracarboxylate framework material

Reported here is an anionic framework material [(CH3)2NH2]2[Cd3(BPTC)2]. (DMF) (1), which features a pillared-layer structure with 1D channels occupied by the guest [(CH3)2NH2]+ cations. The physical properties such as thermogravimetric analyses (TGA), powder X-ray diffraction (PXRD), and gas adsorption were investigated. Additionally, we find that compound 1 may act as a good luminescent sensor to detect the Tb3+ ion.
