Solution processed ter-anthrylene-ethynylenes for annealing-activated organic field-effect transistors: A structure-performance correlation study

Article abstract of DOI:10.1039/c1jm11957e

OFETs based on new solution-processed ester functionalized 9,10-ter-anthrylene-ethynylenes show a mobility increase of four orders of magnitude, leading to mobilities as high as 4.9 × 10^-2 cm ² V^-1 s^-1 if the deposited film is annealed before contact deposition. The behavior is ascribed to an increase in film order at the dielectric/semiconductor interface as revealed by X-ray studies.
