Two conjugated polymers using 5,6-dialkoxy benzothiadiazole derivatives as the dopant were synthesized and studied as electroluminescent materials. These two polymers were well characterized by ¹H NMR, UV–Vis absorption spectrum, gel permeation chromatography, fluorescent spectrum and cyclic voltammetry. The electron mobility and electroluminescent properties were also investigated. The highest external quantum efficiency and luminous efficiency were improved by two orders of magnitude facilely via incorporating benzothiadiazole unit in the main chain.

通过并入苯并二噻唑单元获得高效红色发光聚合物的有效方法

合成了两种以5,6-二烷氧基苯并噻二唑衍生物为掺杂剂的共轭聚合物，并作为电致发光材料进行了研究。通过¹ H NMR，UV-Vis吸收光谱，凝胶渗透色谱，荧光光谱和循环伏安法对这两种聚合物进行了很好的表征。还研究了电子迁移率和电致发光性质。通过在主链中引入苯并噻二唑单元，可以轻松地将最高外部量子效率和发光效率提高两个数量级。
