Abstract
Anisotropic scattering patterns have been observed from organic thin films that are isotropic on the scale of the probe in polarized resonant X-ray scattering experiments. The symmetry is broken by local correlations between molecular orientation and domain structure interacting with polarized X- rays. Two morphological paradigms potentially exhibiting these effects, each of high interest in organic electronics, are simulated. These simulations reveal that detailed examination of the anisotropy allows unambiguous identification of the alignment mechanism and that anisotropy is distinct from and complementary to isotropic scattering intensity as a measure of thin film microstructure.Citation
