Asymmetrically 4,7-disubstituted benzothiadiazole derivatives involving a carbazolyl moiety at one end and a solubilizing dendron at the opposite end have been synthesized and characterized. A two-layer electroluminescent device based on one of these solution-processed molecular emitters revealed a maximal luminous efficiency of approximately 10.6 cd A(-1) and green light emission with CIE coordinates (0.34, 0.58).
不对称地 4,7-取代苯并噻二唑衍生物在一端含有咔唑基部分，在另一端含有一个可溶解的树枝状大分子。一个基于这些溶液处理的分子发射器的双层电致发光器件显示出最大的发光效率约为 10.6 cd A(-1)，并且具有 CIE 坐标 (0.34, 0.58) 的绿光发射。
