摘要：

Blue electrophosphorescence in organic light-emitting diodes (OLEDs) is enhanced by the use of 3,6-bis(triphenylsilyl)carbazole (see figure). This carbazole derivative with sterically bulky and large-gap triphenylsilyl groups is an electrochemically and morphologically stable efficient host material for blue electrophosphorescence. When utilized in OLEDs, high efficiencies of up to 16 %, 30.6 cd A(-1), and 26.7 Im W-1 are achieved.
