  High charge mobility in active layers of organic electronic devices is often
necessary for their efficient operation. As a result, search for high-mobility
materials among the plethora of synthesizable organic semiconductors is of
paramount importance for organic electronics. However, a model for rapid but
reliable prediction of charge mobility in various organic semiconductors is
still lacking. To solve this issue, we propose a simple analytical model that
considers the most essential factors governing the charge transport in these
materials: intermolecular electronic coupling, charge delocalization,
electron-phonon interaction, and static and dynamic disorder. The suggested
model efficiently predicts charge mobility for organic semiconductors of
various chemical structures and sizes, and significantly outperforms another
approach usually used for screening of organic semiconductors, - Marcus model,
- which overlooks high-mobility materials possessing small conjugated cores. We
thus anticipate that the suggested model is an efficient tool for the search of
the high-mobility organic semiconductors, and its possible integration with
crystal structure prediction can boost the development of organic electronics.
