A new heterometallic Cd(II)–Ba(II) coordination polymer, namely [Cd₂Ba(bptc)₂(H₂O)₄]_n·3n(H₂O)·n(DMA) (1, H₃bptc = biphenyl-3,4′,5-tricarboxylic acid, DMA = N,N′-dimethylacetamide), was successfully prepared via the solvethermal reaction of Cd(II) ions, Ba(II) ions and H₃bptc. Interestingly, compound 1 shows high selectivity and sensitivity toward Cu²⁺ ions in DMA medium via the luminescence quenching. The application values of the new compounds on the psoriasis metabolic syndrome were evaluated and the mechanism of the compound was also discussed.
