Multi-functional Photoelectric Sensor Based on a Three-fold Interpenetrated Cd(II) Coordination Polymer for Sensitive Detecting Different Ions
Athree-fold interpenetrated cadmium coordination polymer [Cd3(BTC)2(H2O)9]·2H2O(CP 1)(H3BTC=1,3,5-benzenetricarboxylic acid) was selected and synthesized to investigate its photoelectric properties. CP 1 showed excellent sensitivity for Cr2O7 2− and Fe3+, low limit of detection(LOD: 0.39 µmol/L for Cr2O7 2− and 1.72 µmol/L for Fe3+) and stability as electrochemical sensor. More importantly, fluorescence sensing studies indicated that CP 1 exhibits sensing activity for Fe3+, Fe2+, and MnO4 − with good cyclic stability and selectivity. Low LOD and high-sensitivity capability of CP 1 make it a potential multifunctional photoelectric sensor.
