| Abstract: | A novel synthetic route for N, N'-tetrakis(m-biphenyl) -4, 4 '-benzidine (m-TBPBz) and itsapplication as a hole transport material in organic electroluminescent (EL) device are presented. Thedevice structure of glass substrate/indium-tin oxide( 130 nm)/m-TBPBz (40 nm)/tris(8-hydroxyquino-linolato) aluminum (Ⅲ) (Alq, 60 nm) /LiF (0.5 nm)/Al (100 nm) was fabricated. The EL deviceexhibited bright green light with a peak wavelength at 532 nm originating from Alq and a maximum lu-minance of 9 486 cd/m2 at 10.0 V. |
