Tremendous progress toward high-performance organic electronics has been achieved to date by increasing charge carrier mobility through rational designs of organic molecules, crystallinity/morphology control, and optimization of device structures. In organic semiconductors, the intermolecular stacking arrangement, such as π-π stacking distance and π-π overlap level plays an important role in the intrinsic carrier mobility. Therefore, we have systematically investigated the relationship between carrier mobility and intermolecular configurations, π-π stacking distance and π-π overlap level, for two representative organic semiconductors, TIPS-PEN and PTCDI-C8. In these works, we observed monotonic and periodic change of carrier mobility with respect to intermolecular configurations. Furthermore, we elucidated the origin of periodic behaviors of carrier mobility in molecular orbital interactions. |
