On page 2357, Y. L. Loo and co‐workers demonstrate access to two distinct packing motifs in thin films of a molecular semiconductor through post‐deposition processing. The combination of selected‐area electron diffraction and grazing‐incidence X‐ray diffraction tracks the reversible transformation between them, and suggests polymorphs with smaller in‐plane anisotropy are more beneficial for efficient lateral charge transport in polycrystalline devices.
