Benzothiazole-based heterodipodal chemosensor for Cu2+ and CN– ions in aqueous media

A selective chromone‐based colorimetric chemosensor for detecting Cu2+ in near‐perfect aqueous solution and test kit

“…However, low or excessive concentrations of Cu 2+ in body could induce diversely serious troubles like arthritis, Parkinson's disease, anemia, Wilson's disease, and Menkes syndrome [11–14]. Since copper ions could be accumulated in the human body through drinking water, therefore, the World Health Organization (WHO) has set a maximum permissible copper‐ion level of 2 mg/L for drinking water [15–17]. Thus, it is exceedingly important to develop analytical tools that can precisely detect trace amounts of copper ions in aqueous environment.…”

A new sensitive and selective detection of Ga3+ by thiophene‐based ‘turn‐on’ fluorescent chemosensor

“…[ 19,20 ] In contrast with these methods, fluorescent chemosensors that target the metal ion can be appropriately probed via fluorescence variation and have advantages such as specificity, simplicity, and ease of handling. [ 21–24 ]…”

“…They adopt several moieties for instance, rhodamine, sulfonamide, quinolone, benzothiazole, and a naphthyl group. [ 5,6,23–39 ] However, some of them are restricted by the use of complex synthetic methods of preparation. Thiophene derivatives with good optical properties could be used as a functional group for chemosensors.…”

Construction of a Quinoline‐based Sequential Functioning Chromogenic Sensor for Copper(II) Ion and Biothiols: Its Application to Test Strips

“…Therefore, the effective method for detecting them has attracted considerable attention 1,2 . As one of the abundant metal ions, copper ion plays an essential role in human metabolism and environments 3,4 . Its impact on homeostasis is of great significance, but over‐accumulation of concentration of copper ion can threaten human health through genetic disorders like Menkes's and Alzheimer's disease 5,6 .…”
