A single chemosensor for multiple target anions: The simultaneous detection of CN− and OAc− in aqueous media

Novel chemosensor for multiple target anions: The detection of F− and CN− ion via different approach

“…While each chemosensor showed some advantages such as easy synthesis, high sensitivity, no interference and naked eye detection. Our receptor 1 exhibited quite appealing analytical features such as easy synthesis, high selectivity and naked-eye sensing (R15 5CN À ) [29][30][31][32][33][34].…”

A new Dual-Channel Chemosensor Based on Chemodosimeter Approach for Detecting Cyanide in Aqueous Solution: a Combination of Experimental and Theoretical Studies

“…1b). These results proposed that CN − might attack the imine group of 1 via a nucleophilic addition mechanism, resulting in colorless [38,64,65].…”

“…of CN − , and a clear isosbestic point was observed at 288 nm. A noticeable decrease of the absorption band at 400 nm suggested that the transition of ICT might be interrupted by the nucleophilic addition reaction of CN − to 1 (Scheme 2) [38,64,65]. The Job plot [69] referred to a 1:1 stoichiometry between 1 and CN − (Fig.…”

Chelate-type Schiff base acting as a colorimetric sensor for iron in aqueous solution

“…Stoichiometry of the 1-Fe 2+ complex was determined by Job plot [43][44][45] which revealed 1:1 ratio as shown in the 1-Fe 3+ complex. (Fig.…”
