Dibenzo[g,p]chrysene: A new platform for highly efficient red phosphorescent organic light-emitting diodes

One polycyclic aromatic hydrocarbon compound, 3,6,11,14-tetraphenyldibenzo[g,p]chrysene (TPDBC), was designed, synthesized, and fabricated in a red phosphorescent organic light-emitting diode (PHOLED) with a maximum external quantum efficiency (EQE) of 14.4%, which represented the first report of a dibenzo[g,p]chrysene motif as the building block for host materials. It was conjectured that dibenzo[g,p]chrysene may serve as a next generation molecular platform which is readily functionalizable for the preparation of electroactive materials for applications in the emerging areas of molecular electronics.
