Abstract

A novel blue light-emitting material, di-spiro-9,9′-di-fluorene-9″,9‴-(9,10-dihydro-anthracene), has been synthesized and fully characterized. Organic electroluminescent (EL) cells have been fabricated using this spiro-annulated compound as the emitting layer with N,N′-di(α-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4 ′-diamine (NPB) and/or 4,4′,4″-tris(3-methylphenyl-phenylamino)-triphenylamine (m-MTDATA) as the hole transport layer. Pure blue emission with a maximum luminous efficiency up to 4.73 lm/W (15.1 cd/A) has been achieved, demonstrating that this compound might be a suitable blue lightemitter for fabricating blue organic EL devices.
