Beschreibungen/Notizen

• Combining a strong donor, tris(dodecyloxy)phenyl)-dithieno[3,2-b:2′,3′-d]pyrrole, with a strong acceptor, 4,8-dithien-2-yl-2λ4δ2-benzo[1,2-c;4,5-c′]bis[1,2,5]thiadiazole, has yielded the lowest bandgap, soluble, spray-processable polymer to date. The polymer has access to four different redox states and shows ambipolar behavior in OFETs. Multiple techniques, including transmission/absorption spectroscopy on SWCNTs and reflectance spectroscopy on gold were used to accurately estimate the optical bandgap at 0.5−0.6 eV, which correlates well to theoretical calculations.
