A new multifunctional rhodamine-derived probe for colorimetric sensing of Cu(II) and Al(III) and fluorometric sensing of Fe(III) in aqueous media

A novel diarylethene-based fluorescent “turn-on” sensor for the selective detection of Mg2+

“…Hence, it is vital to design highly selective, sensitive, and simple sensors that can recognize Mg 2+ without the interference of Ca 2+ . 43,44 Among the reported uorescence sensors, [45][46][47][48][49][50][51][52][53][54] diarylethene derivatives are the most promising candidates owing to their excellent thermal stability, remarkable fatigue resistance, and rapid response time. [55][56][57] Furthermore, the recognized ions could induce a stable transformation between diarylethene molecule and complex, and these properties make it possible for the application in logic gates.…”

Rhodamine 6G hydrazone with coumarin unit: a novel single-molecule multianalyte (Cu2+ and Hg2+) sensor at different pH value

“…18 The detection methods for numerous metal ions with differential responses are more efficient and less expensive than one-to-one analytical methods. [38][39][40][41] Hg 2+ is one of the most toxic metal ions. When present in soil or effluent water, Hg 2+ is assimilated and converted by lower-order aquatic organisms into methylmercury, which is one of the most potent neurotoxins to humans.…”

A simple and facile colorimetric chemosensor for selective detection of Cu2+ ion in aqueous solution

“…Consequently, a large number of papers involving colorimetric chemosensor [18][19][20][21][22][23], fluorescent chemosensor [24][25][26][27][28][29] and other techniques [30][31][32][33][34][35] have been published for metal ion detection. In recent themed issue series of Chemical Society Reviews on sensor targets and imaging agents also confined an exciting mix of reviews focusing on small organic or transition metal receptors.…”
