Substituted hexabenzocoronenes (HBCs) form films with supramolecularly ordered columnar stacks that are uniaxially oriented onto poly(tetrafluoroethylene) alignment layers (see Figure). In field-effect transistor (FET) tests, mobilities of up to 10–3 cm2 V–1 s–1 and high on–off ratios of more than 104 were derived for these aligned HBC films, characteristics superior to FETs prepared from isotropic HBC layers.
