| Abstract: Two zinc/cadmium-based coordination polymers (CPs),[Zn (FDC)(DMF)2]n(1) and{(Me2NH2)2[Cd2(FDC)3(H2O)2]·4H2O}n(2)(H2FDC=2,5-furandicarboxylic acid,DMF=N,N-dimethyl formamide) have been prepared based on 2,5-furandicarboxylate under the same reaction conditions (130℃ and DMF) and were structurally characterized by elemental analysis,IR,TGA,powder X-ray diffraction and single-crystal X-ray diffraction.Complex 1 performs a 1D chain structure,where the chains are further connected into 2D layer structure by hydrogen bonds,whereas 2 shows 2D (4,4) network and is unstable in air.The results of thermal analysis indicate that 1 is stable up to 300℃ after the DMF molecules are removed,but 2 is unstable after the aqua ligands,cations and solvent molecules are removed.Moreover,the luminescent properties of 1 and 2 were detected at room temperature under the excitations of 303 nm and 350 nm,respectively.Both of 1 and 2 emit the intensely blue characteristic luminescence at room temperature (λmax=406 and 470 nm),with lifetimes of up to 76.2 and 138.1 ns,respectively.CCDC:1489352,1;1527106,2. |
