Colorimetric and electrochemical sensing for fluoride anion by ferrocenyl-based imidazole compound with electron donor–acceptor structure

Colorimetric and electrochemical sensing for fluoride anion by ferrocenyl-based imidazole... In this paper, a new ferrocenylimidazole compound L was designed and synthesized. L could selectively sense a fluoride anion among test anions such as F−, AcO−, Cl−, Br−, I− and HSO4 −, accompanied by obvious color or electrochemical changes. The detection limit in a DMSO solution was calculated as 5.94 × 10−6 M−1. From the Uv–vis, NMR and electrochemical titrations, it was indicated that L and fluoride anions formed a 1:1 complex with hydrogen bonding and anion–π interactions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

In this paper, a new ferrocenylimidazole compound L was designed and synthesized. L could selectively sense a fluoride anion among test anions such as F−, AcO−, Cl−, Br−, I− and HSO4 −, accompanied by obvious color or electrochemical changes. The detection limit in a DMSO solution was calculated as 5.94 × 10−6 M−1. From the Uv–vis, NMR and electrochemical titrations, it was indicated that L and fluoride anions formed a 1:1 complex with hydrogen bonding and anion–π interactions.
