Study on optical recognition and electrochemical sensing of a 1,1 '-ferrocenedicarbonylhydrazine derivative for fluoride

Abstract

A new compound, 1,1'-di-(p-nitrophenylhydrazino-beta-carbonyl)-ferrocene (1) was designed as an anion receptor based on its hydrogen bonding interaction with anions. Investigation of UV-vis spectra showed that it was an excellent optical sensors for F-. Furthermore, the nature of interaction between it and F- was investigated by H-1 NMR titration experiments. In addition, the efficiency of the receptor applied as an electrochemical sensor for F- was discussed by cyclic voltammetry (CV). Copyright (C) 2008 John Wiley & Sons, Ltd.
