摘　　要：Athree-fold interpenetrated cadmium coordination polymer[Cd_(3)(BTC)_(2)(H_(2)O)_(9)]·2H_(2)O(CP 1)(H_(3)BTC=1,3,5-benzenetricarboxylic acid)was selected and synthesized to investigate its photoelectric properties.CP 1 showed excellent sensitivity for Cr_(2)O_(7)^(2−)and Fe^(3+),low limit of detection(LOD:0.39µmol/L for Cr_(2)O_(7)^(2−)and 1.72µmol/L for Fe^(3+))and stability as electrochemical sensor.More importantly,fluorescence sensing studies indicated that CP 1 exhibits sensing activity for Fe^(3+),Fe^(2+),and MnO_(4)−with good cyclic stability and selectivity.Low LOD and high-sensitivity capability of CP 1 make it a potential multifunctional photoelectric sensor.
