Journal ArticleDOI
Progress with Light-Emitting Polymers
TL;DR: In this article, the authors present a review of light-emitting polymers as materials for lightemitting diodes (LEDs) and present a two-layer device structure for commercial polymer LEDs as well as polyfluorene.
Journal ArticleDOI
Correlating structure with fluorescence emission in phase-separated conjugated-polymer blends.

TL;DR: The use of scanning near-field optical microscopy, scanning force microscopy and nuclear-reaction analysis to study the structure of a thin film of a phase-separated blend of two conjugated polymers prepared by spin-casting shows that in addition to the well-known micrometre-scale phase- separation morphology, one of the polymers preferentially wets the surface and forms a 10-nm-thick, partially crystallized wetting layer.

Crosslinkable arylamine compounds and conjugated oligomers or polymers based thereon
TL;DR: Crosslinkable arylamine compounds, oligomers and polymers prepared from such crosslinkable annealing compounds; films and coatings; and multilayer electronic devices comprising such films are disclosed in this paper.

TL;DR: In this article, a modified Suzuki coupling process is used to synthesize RGB fluorene-based homopolymers and copolymers for light-emitting diodes.
Patent
Halogenated bisdiarylaminopolycylic aromatic compounds and polymers thereof
TL;DR: A halogenated bisdiarylaminopolycyclic aromatic compound, polymers made therefrom, and polymeric light emitting diode devices using the polymers are described in this paper.
