A multilayer blue-emitting organic electroluminescent (EL) device using 5,5
'-bis(dimzsityl-boryl)-2,2'-bithiophene (BMB-2T) as a blue-emitting amorpho
us molecular material and 4.4'.4 "-tris(3-methylphenylphenylamino) tripheny
lamine (m-MTDATA) and tri(o-terphenyl-4-yl)amine (o-TTA) as hole-transporti
ng amorphous molecular materials was fabricated. The multilayer EL device,
ITO/m-MTDATA(300 Angstrom)/o-TTA(200 Angstrom)/BMB-2T(200 Angstrom)MgAg, em
itted bright-blue light resulting from BMB-2T, exhibiting relatively very h
igh performances with a maximum luminance of 1700 ed m(-2) at a driving vol
tage of 17 V and luminous and external quantum efficiencies of 0.08 lm W-1
and 0.24%, respectively, at a luminance of 300 ed m(-2). (C) 2000 Elsevier
