Journal ArticleDOI
Induction of Circularly Polarized Electroluminescence from an Achiral Light-Emitting Polymer via a Chiral Small-Molecule Dopant
Ying Yang,Rosenildo Correa da Costa,Detlef-M. Smilgies,Alasdair J. Campbell,Matthew J. Fuchter +4 more
TL;DR: By simply doping the conventional light-emitting polymer F8BT with a helically chiral aromatic molecule, it is shown that substantial levels of CP-electroluminescence can be generated directly.
Journal ArticleDOI
Circularly Polarized Phosphorescent Electroluminescence with a High Dissymmetry Factor from PHOLEDs Based on a Platinahelicene.
TL;DR: The dissymmetry of CP emission reached with this proof-of-concept single-layer helicene-based device is sufficient to provide real-world benefits over nonpolarized emission and paves the way toward chiral metal complex-based CP-PHOLED displays.
Journal ArticleDOI
Polymer Field‐Effect Transistors Fabricated by the Sequential Gravure Printing of Polythiophene, Two Insulator Layers, and a Metal Ink Gate
Monika M. Voigt,Alexander Guite,Dae-Young Chung,Rizwan U. A. Khan,Alasdair J. Campbell,Donal D. C. Bradley,Fanshun Meng,Joachim H. G. Steinke,Steve Tierney,Iain McCulloch,Iain McCulloch,Huguette Penxten,Laurence Lutsen,Olivier Douheret,Jean Manca,Ulrike Brokmann,Karin Sönnichsen,Dagmar Hülsenberg,Wolfgang Bock,Cécile Barron,Nicolas Blanckaert,Simon Springer,Joachim Grupp,Alan Mosley +23 more
TL;DR: The mass production technique of gravure contact printing is used to fabricate state-of-the-art polymer field-effect transistors (FETs) as discussed by the authors using plastic substrates with prepatterned indium tin oxide source and drain contacts.
Journal ArticleDOI
Inverting the Handedness of Circularly Polarized Luminescence from Light-Emitting Polymers Using Film Thickness
Li Wan,Jessica Wade,Francesco Salerno,Oriol Arteaga,Beth Laidlaw,Xuhua Wang,Thomas J. Penfold,Matthew J. Fuchter,Alasdair J. Campbell +8 more
TL;DR: Insight is provided into the mechanisms that result in CP luminescence and high performance from CP-PLEDs, as well as demonstrating new opportunities in CP photonic device design through the control of active layer thickness and device architecture.
Journal ArticleDOI
Emergent Properties of an Organic Semiconductor Driven by its Molecular Chirality
Ying Yang,Beth Rice,Xingyuan Shi,Jochen R. Brandt,Rosenildo Correa da Costa,Gordon J. Hedley,Detlef-M. Smilgies,Jarvist M. Frost,Jarvist M. Frost,Ifor D. W. Samuel,Alberto Otero-de-la-Roza,Erin R. Johnson,Kim E. Jelfs,Jenny Nelson,Alasdair J. Campbell,Matthew J. Fuchter +15 more
TL;DR: It is shown that organic field-effect transistors made from the helically chiral molecule 1-aza[6]helicene can display up to an 80-fold difference in hole mobility, together with differences in thin-film photophysics and morphology, solely depending on whether a single handedness or a 1:1 mixture of left- and right-handed molecules is employed under analogous fabrication conditions.
