Arene-based fluorescent probes for the selective detection of iron

Abstract

Amide based probes containing phenyl (L1), naphthyl (L2) and anthracenyl (L3) groups were screened towards metal ions. Probes L2 and L3 display sensing for Fe2+ and Fe3+ ions. The L3–Fe3+ system is shown to have potential applications in logic gates and cell imaging.

“…Thus we can assume that sensor1 can be used for the application of molecular logic gates, keypads, switches, etc. [10,32,33]…”

An Electrochemical Sensor Based on Gold and Bismuth Bimetallic Nanoparticles Decorated L-Cysteine Functionalized Graphene Oxide Nanocomposites for Sensitive Detection of Iron Ions in Water Samples

“…Hence, iron ion levels are necessarily determined in different fields, such as clinical, drug, and environmental monitoring [ 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. In the past few decades, a large number of methods have been developed and applied to detect iron ions, including flame atomic absorption spectrometry [ 13 ], inductively coupled plasma mass spectrometry [ 14 ], reversed-phase high-performance liquid chromatography [ 15 ], electrochemistry [ 16 , 17 ], colorimetric analysis [ 18 , 19 , 20 ], and fluorescent spectrophotometry [ 21 , 22 , 23 ]. Among these analytical methods, electrochemical analysis has attracted much attention owing to its simple and fast operation, high sensitivity and low cost [ 24 ].…”

Discriminating Chemosensor for Detection of Fe3+ in Aqueous Media by Fluorescence Quenching Methodology

“…[1][2][3][4][5] The high intake or deficiency of metal ions consumed in the human body can cause the serious problem on the human health. [11][12][13] It is well known that iron is the fourth most important transition metal ion in biological systems. To develop such analytical method must be concerned with environmental protection and human health.…”

“…To develop such analytical method must be concerned with environmental protection and human health . Amongst numerous methods used so far for the detection of a metal ion in aqueous solutions, fluorescent sensors with selective and sensitive characteristics are best candidates for onsite quantitative determination of metal ions from ordinary and pharmaceutical samples …”
