| Organic light emitting devices (OLEDs) show promise for use in the display industry, particularly as the active display portion of flat panel televisions and monitors. Unfortunately important material fundamentals of these organics are not well understood, like charge transport, charge injection and exciton formation/relaxation. It is therefore useful to attempt to understand the behavior of these materials in the physical state that they will be used in: thin films. There have been two models proposed to explain charge transport in these materials and it is the purpose of this work to examine them using a group of similar materials. These materials are similar enough to use the same theoretical models on, yet different enough to draw conclusions about those models from the observed differences. |
