摘要:
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.
