A ferrocene-based multi-signaling sensor molecule functions as a molecular switch

摘要

A multi-channel signaling cation sensor R had been achievedby covalently connecting ferrocene unit to the nitrogen (C=N) containing binding site. Ferrocene-based sensor R was synthesized and characterized by spectroscopic methods and single crystal XRD. The chromogenic, flourogenic and electrochemical sensor study of R in CH3CN shows selective binding of Cu~(2+) ion. Inherently molecule R performs as molecular switch beyond the sensing role.
