Symposium EL16-Carrier-Dopant Interactions in Organic Semiconductors—From Fundamentals to Applications

This symposium will bring together experimental and computational researchers to discuss advances in our knowledge of doped organic semiconductors and organic mixed ionic-electronic conductors. Organic semiconductors are typically doped to raise their electrical conductivity by exposing them to molecules—termed dopants—that add or remove electrons. Doping can adversely impact charge transport and the origin of this impact has been studied invoking competing hypotheses. These include the formation of deep traps, energetic disorder from Coulombic interactions between dopant and carriers, charge transfer complexes, and many others. Recent research has demonstrated novel ways to minimize the adverse impact of dopants on transport, ranging from lengthening side chains to increase charge separation, multi-charge transfer, disorder compensation between the polymer and the dopant-induced energetic disorder, as well as numerous other advances. This symposium will focus on these recent advances in doping strategies, doping mechanisms as well as their influence on carrier transport of organic semiconductors and the avenues they open toward better organic electronics, thermoelectrics and photovoltaics. Of particular interest are the studies that probe the impact of polymer and small molecule structure, polymer morphology, dopant structure, additives, and the location of dopants within the polymer on the electronic and charge transport properties. The aim of this symposium is for researchers from diverse backgrounds and locations to come together and openly discuss the recent developments in this area, with the common goals of developing unifying hypotheses and design strategies that can lead to high performance doped organic semiconductors.
