Abstract

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 cm²V^–1s^–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.
