Vertical chain backbone alignment in a semiconducting polythiophene film is illustrated by D. R. Barbero and co‐workers on page 2359. The chain alignment enables fast charge transport and ultrahigh mobility, reaching a record high average mobility of 3.1 cm 2 V −1 s −1 in the vertical direction, showing that mobilities comparable to those of inorganic materials can be obtained over relatively large distances in polymers through control of the polymer chain orientation.
