Senol, Ayse Merve published the artcileSynthesis and photophysical properties of new pyrazolines with triphenyl and ester derivatives, Formula: C9H10O3, the main research area is phenylbenzohydrazonoyl chloride methyl cinnamate diastereoselective dipolar cycloaddition; methyl triphenyl dihydropyrazole carboxylate preparation absorption fluorescence solvatochromism.
New (4S*,5S*)-Me 3-(2,3-dimethoxyphenyl)-5-(3,4-dimethoxyphenyl)-1-phenyl-4,5-dihydro-1H-pyrazole-4-carboxylate and its isomer were synthesized from 1,3-dipolar cycloaddition reaction of a hydrazonyl chloride with a cinnamic acid derivative and solvent effects on absorption and fluorescence properties of the novel synthesized pyrazoline derivatives were studied by UV-Vis. absorption and steady-state fluorescence spectroscopy techniques. The absorption and fluorescence spectra for both isomers showed that solvent structure and polarity have effect on photophsical properties of the isomer mols. Isomers exhibited pos. solvatochromism behavior when the polarity of the solvent was increased from p-Xylene to MeOH. Furthermore, isomers showed very high quantum yields in the solvents except for polar solvents and bromobenzene. Solute-solvent interactions were analyzed by using the solvent polarity parameter (ET(30)) approach, Lippert-Mataga equation, Kamlet-Taft and Catalan multiple linear regression anal. These results revealed that the most contributing factor of solute-solvents interactions for the isomer 4 was the solvent acidity whereas the most contributing factors for isomer 5 was the solvent acidity as well as the solvent polarity.
