Abstract

This work examined the relationship between the zero field carrier mobility and the change in potential distribution caused by different subgroups within a conjugated polymer such as OC1C10 - PPV. It was observed that the potential profiles with different values of energy minimum could have a strong bearing on the trapping of carriers and a shallow profile involving a lesser number deep (trap) states also gave rise to short retention time for the trapped carriers. This had the effect of enhancing the zero field mobility. For the structures examined, it appeared that shorter subgroups attached to the polymer backbone (Structure D) would result in a shallower energy trough and the same effect was observed for a geometrically balanced structure with two subgroups attached to the opposite ends in the polymer backbone (Structure C).
