25th ‐ 27th of September 2017, University of Graz, 8010 Schubertstraße 1,Austria
Scope:
Organic molecules show a strong tendency towards polymorphism, as they are typically weakly bound
by isotropic Van der Waals forces and electrostatic interactions. In organic thin films, crystalline
polymorphs may form which only exist in the vicinity of the substrate and are, therefore, denoted as
(metastable) substrate‐mediated polymorphs (SMPs). These types of polymorphs are important for
conjugated organic molecules which are employed as organic semiconductors in novel opto‐electronic
devices and where the crystal structure within thin films is crucial for the device performance. Also for
pharmaceutical molecules, exploiting substrate‐mediated polymorphism is an emerging field of
research, in the search for new medical formulations with enhanced properties compared with bulk
polymorphs.
The workshop will cover the following topics:
‐ Self‐assembly of molecules at surfaces
‐ Nucleation of molecular crystals at surfaces
‐ Organic thin film processing
‐ Thin film polymorphs of conjugated molecules
‐ Thin film polymorphs of active pharmaceutical ingredients
‐ Crystal structure solution from thin films
‐ Theoretical crystal structure prediction
