Solution-processable n-type organic field-effect transistor (OFET) materials based on carbonyl-bridged bithiazole and dioxocyclopentene-annelated thiophenes.
A series of electronegative π-conjugated compounds composed of carbonyl-bridged bithiazole and alkyl-substituted dioxocyclopenta[b]thiophene were synthesized as a candidate for solution-processable n-type organic semiconductor materials and characterized on the basis of photophysical and electrochemical properties. Cyclic voltammetry measurements showed that the first half-wave reduction potent...
متن کاملSolution-processable organic dielectrics for graphene electronics.
We report the fabrication, at low-temperature, of solution processed graphene transistors based on carefully engineered graphene/organic dielectric interfaces. Graphene transistors based on these interfaces show improved performance and reliability when compared with traditional SiO(2) based devices. The dielectric materials investigated include Hyflon AD (Solvay), a low-k fluoropolymer, and va...
متن کاملSolution-processable dendric triphenylamine nonamers as hole-transporting and hole-injection materials for organic light-emitt
We demonstrated two solution-processable triphenylamine dendric nonamers: the N-atom-centered nonamer (TPA9-1) and the phenyl-centered nonamer (TPA9-2). The materials were found to have high glass transition temperature (Tg) up to almost 200°C. The fractional difference of the central units of the molecular structures caused different adaptability due to the different ionization potentials (Ip)...
متن کاملSolution-processable n-type and ambipolar semiconductors based on a fused cyclopentadithiophenebis(dicyanovinylene) core.
Two fused cyclopentadithiophenebis(dicyanovinylene) derivatives (FCPDT-16 and FCPDT-C24) with a low-lying LUMO energy level (3.88 eV) and a rigid core structurewere successfully synthesized.They have good thermal stability and form highly ordered packing structures both in the bulk solid state and in thin films. The field effect transistors fabricated from a solution of these two compounds show...
متن کاملOrganic photovoltaics incorporating fulleroisoquinolinones as n-type materials.
Fulleroisoquinolinones have been synthesized by palladium-catalyzed annulation of N-alkyl benzamides with C(60). A device incorporating fulleroisoquinolinones and the conjugated polymer P3HT exhibited power conversion efficiency up to 2.3% under AM 1.5G irradiation.
