    Project supported by the Science and Technology Research Key Project of Education Department of Henan Province (No. 14A150009), the Science and Technology Plan Project of Zhengzhou City (No. 141PPTGG398) and the Doctor Research Project of Zhengzhou University of Light Industry (No. 2013BSJJ017).

Poly(2,7-N-dodecyl-carbazole)-co-(4,6-2,1,3-benzothiadiazole) (P1) was synthesized for the first time with Suzuki condensation polymerization by introducing 4,6-2,1,3-benzothiadiazole unit. The UV, PL spectra and cyclic voltammetry (CV) curve of P1 were tested. Compared with its 4,7-linked polymer HBC, the higher molecular weight Mn=12000 of P1 was obtained. The UV and PL spectrum shown that the maximum absorption wavelength and photoluminescence of P1 in toluene solution had blue shift about 78 and 43 nm, respectively. The optical bandgap and electrical bandgap increased about 0.35 and 0.40 eV, respectively while the shape of CV curves were similar. It suggested that the solubility of benzothiadiazole based polymer materials was improved effectively and the optoelectrical properties were tunable efficiently by introduction of 4,6-benzothiadiazole unit. It would supply a new method to realize multiple performance tunable of benzothiadaizole based polymer materials.

Key words: 4,6-2,1,3-benzothiadiazole, multiple performance tunable, polymer, optoelectrical functional materials
