摘要

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 mixedwith 5,7-bis(5-bromothiophen-2-yl)-2,3-bis(4-(2-ethylhexyloxy) phenyl) thieno[3,4-b]pyrazinerepeated units [P3] have been prepared following Suzuki polymerisation procedures. The route ofsynthesis and characterisation techniques of this novel class of materials, together with their photo- physical and electrochemical properties are presented in this study. The polymers were characterised1 13 by H NMR, C NMR and Elemental Analysis. Molecular weights were estimated using gelpermeation chromatography (GPC). The thermal stability behaviour for polymers was investigatedusing thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The electronicand photo-physical properties were investigated by use of cyclic voltammetry (CV) and UV-Visspectroscopy, respectively.
