Highly selective and sensitive ‘on-off’ fluorescent chemosensor for Fe3+ ions crafted by benzofuran moiety in both experimental and theoretical methods was written by Madhu, P.;Sivakumar, P.;Sribalan, Rajendran;Arumugam, Senthil M.. And the article was included in Luminescence in 2022.Category: benzofurans This article mentions the following:
A benzofuran glycinamide-based chemosensor, 3-(2-([4-fluorobenzyl]amino)acetamido)benzofuran-2-carboxamide (BGA) was developed and synthesized for the selective and sensitive detection of Fe3+ ions. The photophys. properties of the probe BGA were studied using UV-visible light absorption and fluorescence spectrophotometers. The chemosensor BGA showed a marked ‘on-off’ fluorescence response toward Fe3+ ions in the presence of other metal ions in DMSO/H2O solution (9/1, volume/volume). The very low limits of detection (LOD) were calculated to be 10 nM and 43 nM using UV-visible light absorption and fluorescence spectrophotometers, resp. Job’s plot anal. revealed the formation of a BGA-Fe3+ complex with a 1:1 binding stoichiometry ratio using UV-visible light spectroscopy. The sensing mechanism was also demonstrated using d. functional theory calculation In the experiment, the researchers used many compounds, for example, 3-Aminobenzofuran-2-carboxamide (cas: 54802-10-7Category: benzofurans).
3-Aminobenzofuran-2-carboxamide (cas: 54802-10-7) belongs to benzofurans derivatives. Benzofuran is the “”parent”” of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants. Benzofurans have also made significant and distinctive contributions to biology. They exhibit several biological activities that range from antiviral, antimicrobial, antitumor, anti-inflammatory.Category: benzofurans
