Synthesis and scintillating efficiencies of 2,5-diarylthiazoles with intramolecular hydrogen bond

The synthesized of 2,5-diarylthiazoles with intramolecular hydrogen bond fluoresce at long wavelengths, show abnormally large Stokes' shifts and good radiation resistance. A series of 2,5-diarylthiazole derivatives exhibiting an intramolecular hydrogen bond has been synthesized. The scintillati...

Description
Summary:	The synthesized of 2,5-diarylthiazoles with intramolecular hydrogen bond fluoresce at long wavelengths, show abnormally large Stokes' shifts and good radiation resistance. A series of 2,5-diarylthiazole derivatives exhibiting an intramolecular hydrogen bond has been synthesized. The scintillation efficiency of each member of the series has been determined relative to 2,5-diphenyloxazole. Introduction of an OH group in ortho positions of 2,5-diphenyloxazole and 2,5-diphenylthiazole has led to a red shift of the fluorescence spectra due to intramolecular hydrogen bond, as supported by quantum chemical calculations.
