Conjugated Copolymers of Vinylene Flanked Naphthalene Diimide
Fe, Zhupingi; Han, Yang; Martin, Jaime; Scholes, Fiona H.; Al-Hashimi, Mohammed; AlQaradawi, Siham Y.; Stingelin, Natalie; Anthopoulos, Thomas D.; Heeney, Martin... more authors ... less authors ( American Chemical Society , 2016 , Article)We report the synthesis of a novel naphthalene diimide (NDI) monomer containing two (tributylstannyl)vinyl groups. The utility of this building block is demonstrated by its copolymerization with five different electron-rich ... -
Doping of Large Ionization Potential Indenopyrazine Polymers via Lewis Acid Complexation with Tris(pentafluorophenyl)borane: A Simple Method for Improving the Performance of Organic Thin-Film Transistors
Han, Yang; Barnes, George; Lin, Yen-Hung; Marti, Jaime; Al-Hashimi, Mohammed; AlQaradawi, Siham Y.; Anthopoulos, Thomas D.; Heeney, Martin... more authors ... less authors ( American Chemical Society , 2016 , Article)Molecular doping, under certain circumstances, can be used to improve the charge transport in organic semiconductors through the introduction of excess charge carriers which can in turn negate unwanted trap states often ... -
Indacenodithiazole-Ladder-Type Bridged Di(thiophene)-Difluoro-Benzothiadiazole-Conjugated Copolymers as Ambipolar Organic Field-Effect Transistors
