Anisotropic charge transport : Single‐crystal organic field‐effect transistor devices derived from aggregates of thiophene‐appended porphyrins display very high mobility (0.27 cm 2 V −1 s −1 ). This behavior is due to staircase stacking of the porphyrins with distances between layers of 3.17(7) Å. Furthermore, the charge‐transport behavior is anisotropic owing to an anisotropic molecular arrangement in the single‐crystal microplates.
