摘要

We report bipolar host materials with robust indenocarbazole and biphenyl moiety as hole-electron-transporting unit for phosphorescent yellow organic light-emitting diodes (OLEDs). New host materials demonstrated an excellent morphological stability with high glass transition temperature of 207 ℃ Simultaneously, it also revealed appropriate triplet energy of about 2.6 eV for ideal triplet energy transfer to yellow phosphorescent dopant A phosphorescent yellow OLED with new host ICBP1 (and ICBP2) and conventional yellow dopant iridium(Ⅲ)bis(4-(4-t-butylphenyl)thieno[3,2-c]pyridinato-N,C2')acetylacet-onate (Ir(tptpy)_2acac) shows a low driving voltage of 3.4 (and 3.6 V) at 1000 cd/m~2, and maximum external quantum efficiency as high as 26.4%. Such efficient performance of phosphorescent yellow OLEDs is attributed to a good charge balance and high electron transport properties of host materials.
