采用Suzuki缩合聚合方法, 将4,6-苯并噻二唑单元引入到聚合物中, 合成了4,6-苯并噻二唑-咔唑共聚物P1, 研究了其光学性质和电化学性质. 结果表明, 与4,7-位结构类似物(HBC)相比, P1Mn=12000时仍易溶于甲苯, 二氯甲烷等一般的有机溶剂中; 其薄膜状态时的紫外吸收光谱和光致发光光谱分别蓝移78和43 nm; 光学带宽和电化学带宽分别增大0.35和0.40 eV, 而循环伏安曲线的形状不变; 说明4,6-位苯并噻二唑单元的引入, 有效地改善了苯并噻二唑类聚合物的溶解性能, 调节了光电性能, 但保留了苯并噻二唑单元优异的电化学稳定性和可逆性. 4,6-位苯并噻二唑单元的引入为实现苯并噻二唑类聚合物材料的多性能调节提供了一种新的手段和方法.

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.
