Homogeneous alignment of poly(9,9′-dioctylfluorene) films on rubbed polyimide results in a more than one order of magnitude increase in time-of-flight hole mobility normal to the alignment direction. We find μ = 8.5 ± 1 × 10-3 cm2/V s at an electric field of E = 104 V/cm. Hole transport is found to be nondispersive, indicating a low degree of energetic disorder. © 1999 American Institute of Physics.
