Mobility enhancement in polymer organic semiconductors arising from increased interconnectivity at the level of polymer segments

We present a model to estimate the mobility in polymers and to gauge the effect of increased interconnectivity at the level of polymer segments. The model takes into account the finite length of the polymers and the two-dimensional nature of the transport. These results show that the presence of polymer segments extending from one ordered domain into another can enhance the mobility significantly provided the π-π coupling is sufficiently large.
