Streszczenie:
Organic electronics cover application areas in light emitting diodes, field-effect transistors (FETs) and solar cells which open the window for a novel type of technologies. Organic semiconductors consist of conjugated molecules which can be processed into the electronic devices from solution, allowing large area and low cost fabrication. Moreover, many active compounds are mechanically flexible and therefore applicable to bendable electronic elements. Due to the low cost processing, one-way applications of electronic elements are realizable like radio frequency identification tags and sensors in which FETs play a major role. In these transistors the performance is mainly determined by the speed of the charge carrier transport from one electrode to the other which in turn depends in a great extent on various factors related to the organic semiconductor such as molecular design, supramolecular organization and thin film microstructure. This is the reason why the self-assembly control of the conjugated building blocks over various length scales is essential for the charge carrier migration. This presentation discusses the relation between molecular design and packing, self-assembly during solution processing, microstructure and charge carrier transport for small molecules and polymers.
