In 2012,Dyes and Pigments included an article by Ghanadzadeh Gilani, A.; Moghadam, M.; Zakerhamidi, M. S.; Moradi, E.. Electric Literature of C18H16FNO2. The article was titled 《Solvatochromism, tautomerism and dichroism of some azoquinoline dyes in liquids and liquid crystals》. The information in the text is summarized as follows:
Absorption and emission spectra of three hetarylazoquinoline compounds with different substituents were examined in liquids and liquid crystalline solvents for the first time. The spectral features of the hetarylazoquinoline dyes were explained according to azo/hydrazone tautomerism in conjunction with the solvatochromic characteristic of the preferred tautomer. The nature and extent of solute-solvent interactions were described using Kamlet-Taft and Katritzky multiparameter polarity scales. Solvatochromic azo/hydrazone tautomerism depend on multiple solute-solvent interactions, in particular on specific interactions and the solvent ability to transport the hydrogen atom through the media. In addition, anisotropic hosts prevent shift of the tautomeric equilibrium toward the hydrazone form. In the part of experimental materials, we found many familiar compounds, such as 4-Cyano-3-fluorophenyl 4-butylbenzoate(cas: 86776-52-5Electric Literature of C18H16FNO2)
4-Cyano-3-fluorophenyl 4-butylbenzoate(cas: 86776-52-5) is a member of aromaticfluorinated building blocks. Depending on which substituents are present, fluoroaromatic intermediates can be converted into fluorinated or fluorine-free commercial end products.Fluorine-containing aromatics have been incorporated into drugs (hypnotics, tranquilizers, antiinflammatory agents, analgesics, antibacterials).Electric Literature of C18H16FNO2
