Synthesis and structures of the new biferrocenamine-based receptor and its characterization of electrochemical recognition of transition metal ions

摘要

The new biferrocenamine-base receptor FcL was prepared and characterized.The X-ray crystal structure of FcL was also described.The electrochemical studies reveal that the FcL show a two-wave behavior for H~+,Cu~(2+),Zn~(2+) and Ni~(2+),but was unresponsive to Mg~(2+) and Ca~(2+).The maximum oxidation peak potential shift of about 250 mV was found for FcL in the presence of Cu~(2+),Zn~(2+) or Ni~(2+).
