F. Würthner and team investigate the suitability of twenty dipolar merocyanine dyes as active layer in organic thin‐film transistors on page 44. While the device performance varies significantly up to 0.18 cm 2 V −1 s −1 , it is shown that a good performance of some dyes occurs when they exhibit a high ground state dipole moment and well‐defined sterics, resulting in a beneficial brickwork‐type packing within the thin film.
