Azoaniline-based Rapid and Selective Dual sensor for Copper and Fluoride ions in two different outputmodes of Detection. |
| 초록 |
An azoaniline-containing chemosensor was designed for the efficient and selective detection of Cu2+ and F- in dual sensing modes. The diazotization reaction between 4-aminophenol and 1,3-phenylenediamine led to the formation of (E)-4-((2,4-diaminophenyl)diazenyl)phenol (A1). The hydroxyl group of A1 was protected with tert-butyldimethylsilane, leading to the target probe(A2). This probe showed excellent detection sensitivity and selectivity towards Cu2+ and F- with colorimetric and turn-on fluorescence output signals. Absorption and emission studies were conducted to examine the dual sensing abilities of this probe with the sequential addition of F- followed by Cu2+ and vice-versa. These results showed that the sequential addition of F- followed by Cu2+ resulted in excellent dual sensing responses compared to the other method of addition. A single probe can detect both Cu2+ and F- sequentially as well as independently. |
