Abstract

A highly efficient red electrophosphorescent device exhibited saturated red emission and an impressive external quantum efficiency [eta(ext) = 10.8% (ph/el)] with simple device configuration of doping an iridium complex (Mpq(2)Iracac) into a novel ambipolar spiro-configured donor-acceptor host material (D2ACN) has been developed.
