Abstract Detection of correct oxidation state a metal ion is important to understand its speciation and redox properties. Some rhodamine derivatives can identify Al 3+ , Cr Fe as the trivalent cations. We have synthesized derivative, HL‐qui, from reaction N‐(rhodamine‐6G)lactam‐ethylenediamine with quinoline‐2‐carboxaldehyde for colorimetric well fluorogenic detection all ions +3 such Ga In Tl Gd . presence these cations, colorless nonfluorescent HL‐qui turns pink strongly fluorescent in...
4-Methyl-2-((quinolin-6-ylimino)methyl)phenol and 4-methyl-2-((quinolin-2-ylimino)methyl)phenol have been found to be dual fluorescence chemosensors for Al<sup>3+</sup> Zn<sup>2+</sup> ions, but their sensing ability varies.
A quinoline-based compound, 2,5-dimethylbis(quinolin-2-ylmethylene)benzene-1,4-diamine (DQB), has been found to be a turn-off chemosensor for 2,4,6-trinitrophenol.
Two compounds, namely, 2-hydroxy-5-methyl-3-((pyridin-2-ylimino)methyl)benzaldehyde (HM-2py-B) and 2-hydroxy-5-methyl-3-((pyridin-3-ylimino)methyl)benzaldehyde (HM-3py-B), have been explored as fluorescent chemosensors for pH. HM-2py-B HM-3py-B were synthesized by single step condensation reaction between 4-methyl-2,6-diformylphenol the appropriate aminopyridine. These compounds characterized elemental analysis, FT-IR, 1H NMR, 13C ESI mass spectrometry, absorption fluorescence spectroscopy....
