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 ∼10.6 cd A−1 and green light emission with CIE coordinates (0.34, 0.58)
合成并表征了不对称的4,7-二取代的苯并噻二唑衍生物,其一端为咔唑基部分,另一端为可溶树枝状分子。基于这些溶液处理的分子发射器之一的两层电致发光器件显示最大发光效率约为10.6 cd A -1,并且具有CIE坐标(0.34,0.58)的绿色发光。
