Abstract

The article presents a novel ternary exciplex system based on TCTA dendrimer with a new linking type amongst various functional donors. By linking two donor groups through alkyl chains, this system avoids heterogeneous dispersion and increases solubility. The resulting material, TCTA-O-MCP, forms an exciplex with TPBI, exhibiting a small singlet–triplet splitting energy and longer lifetime. Additionally, this design cleverly depresses the emergence of electromers, acting as another energy leakage channel, by regulating the spatial distance between donors and acceptors. The study opens up new directions for developing exciplex systems in OLEDs, offering improved performance and stability.
