25 August 2008 Materials for organic electronics: conductors and semiconductors designed for wet processing
Author Affiliations +
Organic electronics open new fields of applications requiring large-area coverage, structural flexibility, low-temperature and low-cost processing. A key for this technology is access to suitable materials. Progress in conducting and semiconducting materials for organic electronics will be reported. Highly conductive PEDOT-grades have been developed for high resolution printing. Linear oligomeric and star shaped oligothiophenes will be discussed. These materials show outstanding carge carrier mobility and environmental stability when deposited from vacuum deposition. After fine tuning the deposition parameter by ink jet printing we also obtained transistors with excellent properties. The concept of "flexible core" star shaped oligothiophenes will be discussion which might be a way to combine both, high charge carrier and wet processing.
