FIG. 1.

The HOMO and lowest unoccupied molecular orbitals energy levels of TFB and PFO used for interfacial layers and , PVK, TPD, and PBD components of the LEP compared to the work function of PEDOT:PSS (all referenced with respect to vacuum). The vector in the scheme indicates the direct injection from the TFB interfacial layer into phosphorescent organometallic compound within the LEP.

Upper plot: Current density-voltage characteristics. Lower plot: Brightness-voltage characteristics of the OLEDs under study. The control device is represented with open squares, the devices incorporating a TFB and PFO interfacial layer between PEDOT:PPS represented with solid squares and solid circles respectively.
