dc.description.abstractEnA series of four -conjugated carbazole-alt-benzothiadiazole copolymers (PCBT) were prepared by Suzuki cross-coupling reaction between synthesized dibromocarbazoles as electron-rich subunits and 4,7-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,1,3-benzothiadiazole as electron-deficient subunits. The subunits were directly linked through 2,7- or 3,6- positions of the carbazole. In addition, the carbazole monomers have been N-substituted by a branched or a linear side-chain. The chemical structure of the copolymers and their precursors was confirmed by NMR and IR spectroscopies, and their molar masses were estimated by SEC. Thermal analysis under N-2 atmosphere showed no weight loss below 329 degrees C, and no glass transition was observed in between 0 and 250 degrees C. The band gaps of all PCBTs evaluated by optical spectroscopies and by cyclic voltammetry analysis were consistent with expectations and ranged between 2.2 and 2.3 eV. Finally, 2,7 and 3,6 linkages were shown to influence optical properties of PCBTs.
