The synthesis and characterization of novel donor-acceptor (D-A) type functional dyes is presented. The materials studied are based on the 4-alkoxythiazole structure containing one of three arylamine donor units and one of three acceptor building blocks. The nine dyes were characterized with respect to their photo- and electrochem. properties based on UV/Vis absorption and fluorescence emission spectroscopy, and cyclic voltammetry. D. functional theory calculations were carried out to support these studies. The building blocks used brought their characteristics into the final target structures: the reversible oxidation and electron-donating properties of diarylamines, the high fluorescence quantum yields of 4-alkoxythiazoles, and the low-lying LUMOs of tetraazaanthracenes. Furthermore, by introducing tetraazaanthracenes as the acceptor moiety, narrow band gaps of 1.1 and 0.7 eV were estimated electrochem.
