Journal ArticleDOI
A Binaphthyl–Bithiophene Copolymer for Light‐Emitting Devices
TL;DR: In this article, the properties of a binaphthyl- bithiophene copolymer (PHBNT 2 ) used either as an emitter or as a hole transporter in light-emitting diodes were reported.
Journal ArticleDOI
Low-voltage high-performance organic thin film transistors with a thermally annealed polystyrene/hafnium oxide dielectric
TL;DR: In this paper, lowvoltage pentacene-based organic thin film transistors (OTFTs) are demonstrated with polystyrene (PS)/hafnium oxide (HfOx) hybrid dielectrics.
Journal ArticleDOI
Charge carrier dynamics in metalated polymers investigated by optical-pump terahertz-probe spectroscopy.
TL;DR: Application of the Drude-Smith model allows for estimation of the intrinsic mobility and internal quantum yield of charge carrier generation in these films and thermal annealing is found to have no effect on nanometer scale charge transport.
Journal ArticleDOI
Rhodanine-methine as π-electron acceptor in second-order nonlinear optical chromophores
TL;DR: In this article, the synthesis, electronic absorption and second-order nonlinear optical properties of a series of new dialkylamino electron-donor and rhodanine-methine electron-acceptor substituted conjugated compounds were described.
Journal ArticleDOI
Efficient ultraviolet-blue polymer light-emitting diodes based on a fluorene-based non-conjugated polymer
TL;DR: In this article, an efficient UV-blue polymer light-emitting diodes based on a fluorene-based nonconjugated polymer, poly[2,7-(9,9-dihexylfluorene)-alt-4,4′-phenylether] (PFPE), are fabricated.
