Dibenzofuran-Based Organic Electroluminescent Materials
碩士 === 中國文化大學 === 應用化學研究所 === 95 === A new series of 2,8-disubstituted dibenzofuran derivatives (dbf) have been synthesized via palla¬dium-catalyzed coupling reactions of 2,8-diiodo-dibenzofuran and diarylamines. These compounds are amorphous with a glass transition temperature ranging from 65 to 19...

Two types of double-layer organic light-emitting diodes (OLEDs) were fabricated using these compounds as hole-transporting/emitting layers and TPBI or Alq3 as an elec¬tron-transporting layer: (I) ITO/dbf/TPBI/LiF/Al and (II) ITO/dbf/Alq3/LiF/Al (TPBI = 1,3,5-tris(N-phenylbemimidazol-2-yl)-benzene; Alq3 = tris(8-hydroxy -quinoline)aluminum). In general, type I and type II devices have excitons confined in the hole-transporting and the electron-transporting layers, re¬spectively. Some blue-emitting devices of type I have promising performance. 蔡啟堂 林建村 2007 學位論文 ; thesis 92 zh-TW |
