The results of the studies conducted with the use of stationary and time-resolved fluorescence spectroscopy for the new derivative 2-hydroxy-N-(2-phenylethyl)benzamide (SAL-3) in aqueous solutions with various concentrations of hydrogen ions as well as in solvent mixtures (i.e. media with changing polarity/polarizability) was reported. For the compound selected for the study placed in aqueous solutions with varying concentration of hydrogen ions, the fluorescence emission spectra revealed a single emission band within most of the pH range, however, at low pH (less than 3) a significant broadening (noticeable effect of dual fluorescence) and shifting of the band was observed Whereas, for water and polar (protic) solvents, we observed a very interesting phenomenon of dual fluorescence never before reported for this particular group of analogs (with the specific substituent system). Based on the results of the experiments, it was observed that the presented effects may be related both with conformational effects (related to the possible positioning of the-OH group on the side of the carbonyl system, which facilitates the possibility of proton transfer) as well as, most importantly, the effects of excited state intramol. proton transfer (ESIPT) related in this case with the necessary (new/previously unobserved in published literature) presence of ionic and non-ionic forms of the compound. Both the conducted quantum-mech. time-dependent d. functional theory calculations and excited state dipole moment change calculations for the analyzed mol. in solvents with varying pH confirmed the association between the observed fluorescence phenomena and the two aforementioned effects. In addition to this study using Methyl Salicylate, there are many other studies that have used Methyl Salicylate(cas: 119-36-8Application In Synthesis of Methyl Salicylate) was used in this study.
Methyl Salicylate(cas: 119-36-8) has been used: as a component of clarifying solution for treating Mongolian gerbil cochlea intact for immunofluorescence analysis, as a plant elicitor to test its effect on reducing the whitefly population from tomato plants.Application In Synthesis of Methyl Salicylate
