A yellow fluorescent aluminum complex (Alph(3)) having 4-phenanthridin
olato ligands was synthesized and used as an emitter material in organ
ic electroluminescent (EL) devices. The device structure of glass subs
trate / indium-tin oxide / tetraphenyldiamine derivative / Alph(3) / M
g:Ag was employed. The EL device exhibited bright yellow light origina
ting from Alph(3) with a maximum luminance of 13000 cd/m(2) at 11 volt
.
