Phosphine oxide functionalized pyrenes as efficient blue light emitting multifunctional materials for organic light emitting diodes
In a search for blue light emitting multifunctional materials, the electron transport enhancing diphenyl phosphine–oxide (Ph2PO) group has been appended to blue light emitting pyrene derivatives. This design, we observe, leads to highly efficient electron transporting blue-emitters for non-doped organic light emitting devices (OLEDs) with good film formation characteristics. The superior performance is attributed to enhanced charge transport and formation of pyrene excimers assisted by thermally activated delayed fluorescence (TADF) in the device. We report the synthesis and characterization using experimental and computational methods of six such pyrene derivatives. Although three of these…
