Two-dimensional charge transport in self-organized, high-mobility conjugated polymers
Article Abstract:
The microstructure of 70 nm to 100 nm, spin-coated, regioregular poly(3-hexylthiophene) films has been investigated by grazing-incidence X-ray diffraction on parts of the same SiO2/Si substrates on which field-effect transistor devices were fabricated. It was established that, according to processing conditions, the lamellae can adopt two different orientations - parallel and normal to the substrate - with the mobilities of these orientations differing by more than a factor of 100. Evidence for a connection of high-mobility with two-dimensional charge transport offers a strong basis for investigating supramolecular self-organization to boost charge transport in conjugated polymer semiconductors.

Dendrimers set to self-destruct
Article Abstract:
Dendrimers are artificial macromolecules, constructed in step-by-step fashion using repetitive chemistry. The combination of multivalency with precision architectures has made dendrimers of increasing interest for bio-medical applications, not least for drug delivery.

Helical self-assembled polymers from cooperative stacking of hydrogen-bonded pairs
Article Abstract:
Research is presented concerning the development of functionalized monomer units which form non-covalently linked polymeric structures when associated with alkanes or water. The chain length and helicity of the linked polymeric structures is discussed.
