SPECTRAL-LUMINISCENCE PROPERTIES AND BASICITIES OF 2-(4-PYRIDYL)-5-(4-R-PHENYL)OXAZOLES
The spectral-luminiscence and acid-base properties of 2-(4-pyridyl)-5-(4-R-phenyl)oxazoles were studied.Significant ?-electron conjugation between the individual fragments exists in the molecules of these compounds in solutions at room temperature.Bathochromic and bathofluoric effects, which are particularly appreciable for electron-donor substituents, are observed when substituents R are introducted into the 5-phenyl ring.Ethanol solutions of the investigated compounds have high fluorescence quantum yields which, for some of them, are close to unity.Electron-donor substituents R increase the basicity of the pyridine nitrogen atom.
