Abstract
Official abstract text for this publication.
Novel compounds, and in particular, a dendritic system for improved triple-triplet annihilation upconversion (TTA-UC) are provided. The core of the dendrimer compound includes a metal complex, and on the peripheral, multiple acceptor moieties are covalently linked to the core through a spacer. Consequently, a high efficiency TTA-UC system in both solution and solid state is provided, with particularly high efficiency in the solid state. Additionally, organic light emitting devices (OLEDs) comprising a layer including these novel compounds are provided.
First claim
Opening claim text (preview).
The invention claimed is: 1. A compound for triplet-triplet annihilation upconversion comprising: a metal complex sensitizer core; a first acceptor group; and a first spacer group between the metal complex core and the first acceptor group, wherein the first acceptor group has a first triplet energy lower than a first triplet energy of the metal complex sensitizer core; wherein the metal complex sensitizer core and the first acceptor group are jointly capable of performing t…
