New 2D layered binary Cd(II) coordination polymer applied as luminescent sensor for the detection of acac

A new Cd(II) coordination polymer, namely [Cd(HL)(2)](n) (1, H2L = 4-(pyridin-4-ylsulfanyl)benzene-1,2-dicarboxylic acid) has been hydrothermally synthesized and structurally characterized. X-ray crystallographic analysis revealed compound 1 displays a 2D layered structure with dinuclear [Cd-2(COO)(2)] building subunits, and further layer-to-layer stacking in parallel mode finally results a 3D supramolecular framework. Luminescence property investigation indicated that compound 1 shows intense luminescence under room temperature, and further luminescence sensing experiments demonstrated that 1 can be applied as a good luminescence sensor for the detection of acac with good selectivity and high sensitivity.
