| Popis: | International audience; 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). |
