Controlling self‐organization: The chemical variation of alkyl substituents on the discotic hexa‐ peri ‐hexabenzocoronene allows the molecular orientation to be controlled with respect to a substrate, which is a key prerequisite to implement such semiconductors into electronic devices (see figure). Charge‐carrier mobility determined by a time‐of‐flight technique reveals a high anisotropy along and perpendicular to the established columnar superstructure.
