Firstly, we investigate the influence of the hole injection layer on the performance of the OLED. Evidence shows that m-MTDATA exhibits a dense film structure and fine surface morphology, leading to easy hole migration. Furthermore, a low-voltage driving of OLEDs has been achieved by doping 4F-TCNQ into m-MTDATA layer. Secondly, we obtain a highly efficient OLED by using a new oxidiazoles, an efficient electron-transporting molecular materials. Finally, we have realized the efficient electron injection and transport in organic light-emitting diodes using an electron-transport layer composed of BPhen with Liq co-deposited layer. With this cohost strategy, we improve the power efficiency by～21 % while reduce the driving voltage by～13%.
