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.
