A new coumarin based Schiff-base chemosensor was synthesized and evaluated. Based on Job’s plot,<sup>1</sup>H NMR titration, ESI-MS B-H plot, the structure of ligand its metal ion is 1 : stoichiometry. It also exhibits a binary logic function.
Abstract A mesogenic glycine based Schiff base compound of the type, (E)‐methyl 2‐((2‐hydroxy‐4‐(tetradecyloxy)benzylidene)amino)acetate (HL) has been successfully synthesized and characterized using analytical spectroscopic techniques. The was evaluated for chemosensor activity towards different metal ions fluorescence spectroscopy. experiment reveals highly efficient selective “turn‐on” “turn‐off” responses intensity zinc(II) copper(II), respectively, in presence other ions. binding...
Fluorescence behavior of intramolecular charge transfer probe trans-ethyl-p-(dimethylamino) cinnamate (EDAC) is extremely sensitive to the local environment. This study explores interaction EDAC with several Igepal, Brij and Tween series non-ionic surfactants by steady state picoseconds time-resolved fluorescence spectroscopy. The physico-chemical properties, like critical micelle concentration micropolarity micellar media surrounding were determined. In most cases, observed values in good...
In this study, we employed a combination of steady-state and time-resolved fluorescence spectroscopy studied the site-specific dynamics in GTP aptamer using 2-aminopurine as fluorescent probe. We compared GTP-bound with that free well when it is denatured. binding leads to an overall compaction structure aptamer. The general pattern lifetimes correlation times scanned across several locations does not seem change following binding. However, remarkable narrowing lifetime distribution ensues...
