Abstract
Official abstract text for this publication.
The present invention is directed to solid state organic light emitting devices and to methods for triplet excitation scavenging in such devices. More particularly, the present invention relates to a method for substantially reducing a triplet population in a solid state organic material, the method comprising providing molecules exhibiting non-vertical triplet energy transfer in the solid state organic material or at a distance smaller than a triplet exciton diffusion length from the solid state organic material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for reducing a triplet population in a solid state organic semiconductor material of an organic light emitting device, the method comprising: incorporating, into the organic light emitting device, molecules exhibiting non-vertical triplet energy transfer in the solid state organic semiconductor material or at a distance smaller than a triplet exciton diffusion length from the solid state organic semiconductor material, wherein said molecules e…
