Abstract

We designed an anthracene derivative, disilanyl double-pillared bisanthracene (^SiDPBA) as a new structural motif for carrier transport material for OLEDs. We synthesized ^SiDPBA in a one-step operation from 1,8-diiodoanthracene in 50% yield. The anti-geometry of the anthracene units in ^SiDPBA was revealed by X-ray crystallographic analysis. The device performance of ^SiDPBA as a carrier transport material was evaluated by employing a standard green phosphorescent OLED. The standard device with Alq₃ in electron transport layer (ETL) and a-NPD in hole transport layer (HTL) showed external quantum efficiency (EQE) of 3.4% at the constant current of 2.5 mA/cm², whereas the device with ^SiDPBA in ETL showed superior performance of EQE = 11.0%. Notably, ^SiDPBA functioned not only as an electron transporting material but also as a hole transporting material, and the device with ^SiDPBA both in ETL and HTL effectively operated at EQE of 8.7%.
