Abstract
Organic host-guest structures with a disordered polymer as the host material have various applications
in the field of organic light emitting diodes such as polymeric phosphorescent LEDs or polymeric fluorescent white
LEDs. Effective mobility is a crucial parameter in the simulation of such host-guest OLEDs with conventional
drift-diffusion method. In the present paper, the master equation approach is applied to calculate the effective host
mobility in a host-guest structure and investigate the effect of energy disorder, guest density, charge carrier
density and electric field on this parameter. By employing a parameterization scheme, an accurate model for the
effective host mobility is also derived that can be employed for more precise and realistic simulation of OLEDs
incorporating a host-guest layer with polymeric host.
