Coloquio de Física - Hyperbranched and linear polymers for opto-electronic and organic electronic applications

   Departamentos        Ciencias - Sección Física

Ponente: Brigitte Voit (Technische Universität Dresden, Alemania) The field of organic/flexible electronics is rapidly growing and is influencing significantly our daily life. However, still existing problems, like limited performance and long-term stability of large-area printed devices, lead to a high demand of new, innovative polymeric materials. Besides conducting and semiconducting polymers, also the insulating materials in-between, the dielectrics, as well as polymers with special optoelectronic properties, are of high importance, since they determine significantly the cost-effective processability and the final performance of devices like organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs). We will demonstrate novel semiconductor polymers that are highly interesting as stable active materials of high-performance printed OFETs. In addition, aromatic hyperbranched polymers have been developed as crosslinkable dielectric materials for OFETs and as materials for significantly improving the efficiency in OLEDs by showing Thermally Activated Delayed Fluorescent (TADF) properties or high refractive index (HRI) for increased light out-coupling.
