A novel type of red organic electroluminescent (EL) dye, D-CN with CN group
s and amine groups for an emission layer of electroluminescent devices was
designed and synthesized. Two kinds of EL devices were fabricated. Devices
with a single-layer type, indium tin oxide/D-CN/MgAg and a double-layer dev
ice, indium tin oxide/D-CN/OXD/MgAg were fabricated. D-CN dye shows high EL
efficiency over 1% in red color even in the single-layer device. (C) 2001
