Very high time-of-flight mobility in the columnar phases of a discotic liquid crystal

1,4,8,11,15,18,22,25-Octaoctylphthalocyanine shows the highest time-of-flight (long-range) hole mobility so far reported for the columnar phase of a discotic liquid crystal. Unlike most other high long-range mobility columnar discotics, there is no clear evidence from x-ray diffraction of high order. (C) 2005 American Institute of Physics.
