Research Hot
Topics:
Resonant scattering
of polarized soft x-rays (P-SoXS)
The
collaboration with the group of Prof.
Harald Ade (North Carolina State
University, Raleigh, USA) lead to an
important publication in the latest online
version of Nature Materials. Resonant
scattering of polarized soft x-rays was
used to demonstrate the possibility to
detect orientational order in organic
systems relevant for molecular electronics
on length scales below the present
limitations of x-ray microscopy. P-SoXS
also reveals scattering anisotropy in
amorphous domains of all-polymer organic
solar cells where interfacial interactions
pattern orientational alignment in the
matrix phase, which probably plays an
important role in the photophysics. The
energy and q-dependence of the scattering
anisotropy allows the identification of
the composition and the degree of
orientational order in the domains. For
details, see

Gann, C. Hub, R. Fink, C.Wang, T.
Schuettfort, C. R. McNeill, M. L. Chabinyc
and H. Ade: "Polarized X-ray scattering
reveals non-crystalline orientational
ordering in organic films", Nature
Materials (2012) (http://www.nature.com/nmat/journal/vaop/ncurrent/pdf/nmat3310.pdf)
Electron-vibron-coupling
in halogenated acenapthenequinone
Using
high-resolution NEXAFS the we could get deeper
insight into the intramolecular coupling
mechanism in condensed ANQ films. Latest
experiments show that the localized excitation
in the carbonyl subunit does not couple to
vibronic excitations of the naphthalene core.
The spectral analysis is supported by DFT
calculations. For details, see N. Schmidt et al., J. Chem.
Phys. 135 (2011) 144301.
The
exciting effect of inverse melting has - for the
first time - be demonstrated without applying a
strong external pressure. In collaboration with
physicists at the University of Würzburg, we
could explore this unusual phenomenon which
seems to contradict conventional thermodynamics.
The work has been published in Science on July
16, 2010:
