Selective Fluorescence Sensing of Li⁺ in an Aqueous Environment by a Ferrocene−Anthracene-Linked Dyad

Abstract

A new 1-(9-anthryl)-4-ferrocenyl-2-aza-1,3-butadiene showing selective fluorescence enhancement upon binding to lithium cations over other alkaline cations in aqueous environment has been conveniently synthesized and characterized. [structure: see text]
