Vibrational and electronic properties of the proton transfer fluorophore 2-(5'-amino-2'-hydroxyphenyl)benzothiazole

Abstract

This paper presents the theoretical and experimental study regarding the optical and structural properties of 2-(5'-amino-2'-hydroxyphenyl)benzothiazole. In order to investigate the potential application of this dye in organic light-emitting diodes, a photophysical characterization in film, solution and solid state was performed. Aditionally, Raman and infrared spectroscopies were also applied. The experimental results were compared with theoretical calculations achieved by Gaussian09 software.
