Abstract

A highly efficient red electrophosphorescent device exhibited saturated red emission and an impressive external quantum efficiency [ηext = 10.8% (ph/el)] with simple device configuration of doping an iridium complex (Mpq2Iracac) into a novel ambipolar spiro-configured donor–acceptor host material (D2ACN) has been developed.
