Detection of Ga³⁺ and Cu²⁺ by a Simple Quinoline-Based Bifunctional Chemosensor

A selective sulphur‐containing colorimetric chemosensor for Cu2+

“…[29][30][31][32] In order to selectively detect only Cu 2+ among them, we endowed the sensor APTS with a hard character by using moieties with nitrogen and oxygen atoms. [33][34][35][36] As expected, the sensor APTS detected only Cu 2+ via the colour change from colourless to yellow.…”

“…Sulphur is well known to have a high affinity to Cu 2+ , Ag + and Hg 2+ , and a number of sulphur‐containing sensors have been reported to detect the three metals . In order to selectively detect only Cu 2+ among them, we endowed the sensor APTS with a hard character by using moieties with nitrogen and oxygen atoms . As expected, the sensor APTS detected only Cu 2+ via the colour change from colourless to yellow.…”

A naphthol‐based fluorescence turn‐on sensor for detecting Ga(III) and its application to test strips

“…Most Ga 3+ sensors could sense Group 13 elements together 8,16,17 . Few fluorescent sensors have been reported to detect only gallium, without the interference of Al 3+ or In 3+ 3,18–22 . Therefore, it is essential to develop a new fluorescent sensor, which recognizes only gallium.…”
