title: An unsymmetrically π-extended porphyrin-based single-crystal field-effect transistor and its anisotropic carrier-transport behavior.
abstract: 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.
