Patterns composed of solvent wetting and dewetting regions promote lateral confinement of solution‐sheared and lattice‐strained TIPS‐pentacene crystals. This lateral confinement causes aligned crystal growth, and the smallest patterns of 0.5 μm wide solvent wetting regions promotes formation of highly strained, aligned, and single‐crystalline TIPS‐pentacene regions with mobility as high as 2.7 cm 2 V −1 s −1 .
