Design and synthesis of a novel chromium(III) selective fluorescent chemosensor bearing a thiodiacetamide moiety and two rhodamine B fluorophores

Highly Sensitive Coumarin–Pyrazolone Probe for the Detection of Cr3+ and the Application in Living Cells

“…The observed blue shift and formation of new peak at 575 nm are attributable to coordination of Cr 3+ metal ions with the COPYR probe. Similar types of observations have been documented in several organic moieties in the presence of Cr 3+ ions. − In addition, naked eye colorimetric changes of the COPYR probe in the presence various metal ions were also investigated, and collected observations are presented in Figure B. As shown in Figure B, the probe did not show any observable color change in the solution of different potential interfering metal ions.…”

An anthracene based fluorescent probe for the selective and sensitive detection of Chromium (III) ions in an aqueous medium and its practical application

“…The LOD value of ANT-Th was lower than the other Schiff bases based fluorescent probe, as indicated in Table S1 [22,34,36,41,42]. Similarly, the response time of ANT-Th was quite rapid than other works [24,35,[38][39][40]42]. Moreover, our probe can be the cheapest method as it involves a facile one-step reaction with commercially available chemicals without further complex purification process (Table S1).…”

“…The spectroscopic response of ANT-Th was quite fast (<1 min), and complete saturation was observed after 5 min ( Figure S3). Comparison of the ANT-Th with some other Cr 3+ sensitive fluorescent probes (Table S1) [22,24,[33][34][35][36][37][38][39][40][41][42] clearly shows the superiority of this method. The LOD value of ANT-Th was lower than the other Schiff bases based fluorescent probe, as indicated in Table S1 [22,34,36,41,42].…”

Design and synthesis of a new rhodamine B-based fluorescent probe for selective detection of glutathione and its application for live cell imaging

“…Compound 1 was prepared in an 88% yield from commercially available rhodamine B and ethane-1,2-diamine, as described previously. [47] Compound 2 was prepared in a 51% yield by the reaction of 3,5-diaminobenzoic acid with 3 equiv. maleic anhydride in CHCl3 for 20 h, which was followed by a reaction with acetic anhydride and sodium acetate under refluxing for additional 90 min.…”
