Journal ArticleDOI
Highly efficient phosphorescence from organic light-emitting devices with an exciton-block layer
TL;DR: In this paper, the authors employed starburst perfluorinated phenylenes (C60F42) as both hole and exciton block layer, and a hole-transport material 4,4′,4″-tri(N-carbazolyl) triphenylamine as a host for the phosphorescent dopant dye in the emitting layer.
Journal ArticleDOI
Perfluoropentacene: high-performance p-n junctions and complementary circuits with pentacene.

TL;DR: Perfluoropentacene is a planar and crystalline material that adopts a herringbone structure as observed for pentacene, and the transfer characteristics exhibit a sharp inversion of the output signal with a high-voltage gain.
Journal ArticleDOI
Selective and Random Syntheses of [n]Cycloparaphenylenes (n = 8–13) and Size Dependence of Their Electronic Properties
TL;DR: Redox properties of the C PPs were measured for the first time by using cyclic voltammetry, and the smaller CPPs had lower oxidation potentials, which are consistent with the HOMO energies of CPP's.
Journal ArticleDOI
Synthesis, Characterization, and Electron-Transport Property of Perfluorinated Phenylene Dendrimers

Journal ArticleDOI
Impact of Perfluorination on the Charge-Transport Parameters of Oligoacene Crystals
M. Carmen Ruiz Delgado,Kathryn R. Pigg,Demetrio A. da Silva Filho,Nadine E. Gruhn,Youichi Sakamoto,Toshiyasu Suzuki,Reyes Malavé Osuna,Juan Casado,Víctor Hernández,Juan T. López Navarrete,Nicolas G. Martinelli,Jérôme Cornil,Roel S. Sánchez-Carrera,Veaceslav Coropceanu,Jean-Luc Brédas +14 more
TL;DR: The calculations predict large conduction and valence bandwidths and low hole and electron effective masses in the perfluoroacene crystals, with the largest mobilities expected along the pi-stacks.
