| 摘 要： | A very stable CdⅡ-organic framework,{Cd3(Tipe)1.5(bpodc)2Cl2]·(H2O)2}n(compound 1,Tipe=1,1,2,2-tetrakis(4-(imidazol-1-yl)phenyl)ethene,bpodc=benzophenone-4,4-dicarboxylic acid),has been successfully synthesized under hydrothermal conditions.Compound 1 crystallizes in the triclinic system,space group P1-,with a=12.289(3),b=15.951(4),c=20.755(5)?,α=81.248(2)°,β=83.905(2)°,γ=89.452(2)°,V=3998.2(17)?3,Z=2,Mr=1839.59,Dc=1.528 g/cm3,μ=0.925 mm-1,F(000)=1844,R=0.0508 and wR=0.1571 for 13998 observed reflections(I>2σ(I)).Its overall structure is a three-dimensional stacking with a porosity of 10.1%based on a calculation by PLATON.Compound 1 shows a blue fluorescence emission with the peak maximum of 501 nm(λex=397 nm)by ligand-to-ligand charge transfer of TPE chromophore.And it exhibits excellent performance in detecting Fe3+and Cr2O72-ions in aqueous solutions as a multi-response sensor.
