Multi-properties of a Cu(II) complex: Crystal structure, anion binding ability, bioactivity and cell cytotoxicity
摘要:
A new copper(II) complex based on Schiff bases of 3-nitrosalicylaldehyde was synthesized and the crystal was also obtained fortunately. Its structure was well characterized by single-crystal X-ray diffraction and HRMS. The complex showed the strongest binding ability and high selectivity for hydrogen sulfide among other anions (AcO-, H2PO4-, F-, Cl-, Br- and I-) at neutral pH in organic-aqueous solutions. The possible mechanism was the copper ion was released and combined with hydrogen sulfide after the anion was added. In addition, the further application of the sensor was applied to hela cells cytotoxicity. The above results indicated the copper(II) complex could be used as a sensor for the detection of HS- in the sample of environment, pharmacy, and etc. More importantly, the copper(II) complex also exhibited effective and wide antibacterial activity.
