Figure 6

A schematic that shows each type of TIPS pentacene morphology. (a) Type I: TIPS pentacene crystals with random orientation and poor film coverage. (b) Type II: elongated TIPS pentacene crystals along a uniform direction with improved long-range order and areal coverage. (c) Type III: grass-like, curved TIPS pentacene microwires with interlinkage. The tilting blue rods in (a) indicate the orientation of TIPS pentacene backbones. The red arrows in (a–c) indicate the long axis orientation of TIPS pentacene crystals.
