dc.description.abstract | We designed and synthesized two new ambipolar host materials, namely CzPO and Cz3PO . Combining CzPO and Cz3PO with CzTRZ2 as the emitter resulted in improved maximum external quantum efficiencies of 13.1% and 13.2%, respectively, together with small efficiency roll-offs, while the device based on bis[2-(diphenylphosphino)phenyl]ether oxide ( DPEPO ) as host showed a much more pronounced efficiency roll-off. | |
