An optical and electrochemical anion sensor of F- investigated by UV-vis, H-1 NMR and cyclic voltammetry

Abstract

A new anion receptor: 1,1'-di-(2',4'-di-nitrophenylhydrazino-beta-carbonyl)-ferrocene (1) based on ferrocene has been designed and synthesized as a highly colorimetric and electrochemical sensitive sensor for F-. The binding mode with F- was further investigated by UV-vis titration and 1H NMR titration experiments. In addition, the cyclic voltammetry (CV) was performed to discuss the electrochemical sensing for F-.
