A donor/acceptor series of carbazole copolymers, composed of alternating 2,7-linked 3,6-difluoro-9-(1-octyl-nonyl)-carbazole units and bithiophene repeated units [P1], 5,7-bis(5-bromothiophen-2-yl)-2,3-bis(4-(2-ethylhexyloxy) phenyl) thieno[3,4-b]pyrazine repeated units [P2] and bithiophene mixed with 5,7-bis(5-bromothiophen-2-yl)-2,3-bis(4-(2-ethylhexyloxy) phenyl) thieno[3,4-b]pyrazine repeated units [P3] have been prepared following Suzuki polymerization procedures. The route of synthesis and characterization techniques of this novel class of materials, together with their photophys. and electrochem. properties are presented in this study. The polymers were characterized by 1H NMR, 13C NMR and Elemental Anal. Mol. weights were estimated using gel permeation chromatog. (GPC). The thermal stability behavior for polymers was investigated using thermogravimetric anal. (TGA) and differential scanning calorimetry (DSC). The electronic and photo-phys. properties were investigated by use of cyclic voltammetry (CV) and UV-Vis spectroscopy, resp.
