Organic light-emitting diodes (OLEDs) represent a promising technology for flat-panel displays. Doped ?-conjugated polymer layers have been demonstrated to improve hole injection and lifetime of OLED devices. In this paper, we demonstrate that the work function of such polymers can be continuously adjusted by means of electrochemical doping. This allows to control the hole current through organic semiconducting devices. Injection-limited or bulk-limited device performance can be obtained with the identical semiconductor. We use a combinatorial approach to speed up the optimization process.
