The authors report a sensor, I, for sequentially detecting Zn2+ and CN– based on fluorescence. Sensor I was prepared through the reaction of 3-aminobenzofuran-2-carboxamide with 4-diethylaminosalicylaldehyde. Sensor I1 showed a selective off-on fluorescent response toward Zn2+, distinguishing Zn2+ from Cd2+. The limit of I (0.35 μM) for monitoring Zn2+ is lower than the World Health Organization (WHO) guideline (76 μM) for water available for drinking. Importantly, sensor I could sense Zn2+ in living cells and aqueous media. The resulting I-Zn2+ complex functioned as an efficient on-off sensor for CN–. The mechanisms of I for detecting Zn2+ and CN– were explained by spectroscopic, spectrometric, and theor. studies. In the experiment, the researchers used many compounds, for example, 3-Aminobenzofuran-2-carboxamide (cas: 54802-10-7Application of 54802-10-7).
3-Aminobenzofuran-2-carboxamide (cas: 54802-10-7) belongs to benzofurans derivatives. Many natural or synthetic compounds containing benzofuran skeletons have been found to possess remarkable activity as agrochemicals and pharmaceuticals. They are also prone to polymerisation in the presence of concentrated mineral acids and Lewis acids.Application of 54802-10-7
