Despite decades of intensive research, understanding of the charge transport in high‐mobility organic semiconductors is still a challenge. With a steady advancement in both the experimental and theoretical studies it becomes clear that the charge transport in high‐mobility organic semiconductors is limited by thermally activated low‐frequency vibrations. These vibrations perturb the local environment for a charge carrier and prevent its fast wave‐like motion. In article no. 1800485 , Andrey Sosorev et al. review the most important theoretical and experimental results on low‐frequency vibrations in organic semiconductors and their impact on charge transport. Specifically, the review concentrates on the relationship between the molecular structure, crystal packing, low‐frequency vibrations, and charge mobility. Revealing this relationship is of a paramount importance for the formulation of effective guidelines to minimize the detrimental impact of the low‐frequency vibrations and to focus the search for highmobility organic semiconductors.
