Ligands light up OLEDs

Novel N^C^N-cyclometallated platinum complexes with acetylide co-ligands as efficient phosphors for OLEDs†

Two new cyclometallated platinum(II) complexes have been prepared that incorporate a terdentate N^C^N-coordinating ligand and a monodentate acetylide co-ligand. The complexes, namely [PtL– C^C–C6H3F2] and [PtL 6–C^C–C6H3F2] (where HL 3 1⁄4 5-methyl-1,3-di(2-pyridyl)benzene; HL 1⁄4 5-mesityl-1,3-di(2-pyridyl)benzene; H–C^C–C6H3F2 1⁄4 3,5-difluorophenylacetylene), were prepared by ligand metathes...

A method to determine the presence of oxygen in organic light-emitting diodes (OLEDs)

Organic light emitting diodes (OLEDs) have great potential to replace current commercial display offerings. However, most of the materials comprising the OLEDs suffer degradation effects from the presence of environmental oxygen and water, as both compounds can penetrate into the device. Much research and effort have been put into fabrication methods and proper device encapsulation to help miti...

Efficient Solution-Processed Dendrimer OLEDs

Light-emitting dendrimers are a new distinct class of material for OLEDs. Dendrimers consist of a light-emitting core, dendrons and surface groups. Dendrimers are designed for solution coating and have a number of advantages over conjugated polymers. We report our recent results for solution processed green dendrimer OLEDs. The OLEDs were fabricated by spin-coating a blend of first generation d...
