1. Polymeric Dopants
U.S. Patent 8,562,870 (October 22, 2013), “Polymer Dopants,” Iain McCulloch, Martin Heeney, Mark Giles, Maxim Shkunov, Steven Tierney, and Clare Bailey (Merck Patent GmbH, Darmstadt, Germany).
Charge mobility of organic semiconductors are improved by conductive additives for a host of applications including radio frequency identification (RFID) tags and thin film transistors (TFT) in flat panel displays. One organic semiconducting polymer is regioregular polyalkyl thiophene (PAT). This polymer can be fabricated via solution deposition, to form thin films with a highly ordered morphology, which facilitates charge transfer via a hopping mechanism. Mobility is improved by doping with dichlorodicyano-benzoquinone (DDQ) before fabrication. A major problem with these small molecule dopants is that they can be mobile, diffusing through the polymer film or subliming from the surface McCulloch et al found that polymeric dopants with electron accepting side chain such as quinone are effective.
