Fluorescent and colorimetric sensors for anionic species

Dyes based on the 2(1H)‐quinolone skeleton as potential colorimetric and fluorescent sensors for cyanide anions

“…In recent decades, because of their tremendous application in sensing ions and mercapto biomolecules, fluorescent sensors have been the subject of considerable interest . Recognition of anions to enable their analytical detection is important because of the crucial role they play in living systems and in the environment . Of the various important anions, cyanides are among the most toxic, but they are still widely used in the mining, galvanic and chemical industries .…”

“…[1][2][3][4] Recognition of anions to enable their analytical detection is important because of the crucial role they play in living systems and in the environment. 5,6 Of the various important anions, cyanides are among the most toxic, but they are still widely used in the mining, galvanic and chemical industries. 7 Cyanides are well adsorbed via the gastrointestinal tract or skin, and also by the respiratory track.…”

Tripodal Squaramide Derivative as a Neutral Chloride Ionophore for Whole Blood and Sweat Chloride Measurement

“…The receptors mainly interact with anions by polarized NÀ H fragments that form hydrogen bonding [27][28][29]. These compounds have been studied as anion transmembrane transporters [30][31], fluorescent anion sensors [32][33] and ionophores [25][26] in polymeric membranes. However, the ionophores with sufficient selectivity towards chloride over more lipophilic interfering anions such as salicylate are still lacking for ion sensing in clinical analysis.…”

A novel and fast responsive turn-on fluorescent probe for the highly selective detection of Cd2+ based on photo-induced electron transfer

“…Therefore, the uorescent probe/ sensor has attracted increasing attention for its design and development. [16][17][18][19][20][21][22] Although cadmium ion uorescent probes/ sensors have been reported in literature, [23][24][25][26][27][28] there are still some difficulties that need to be overcome such as the complicated synthesis procedure, poor water solubility and slow response speed.…”
