Blue light-emitting anthracene-based host materials with a spiro[benzo[c]fluorene-7,9′-fluorene] core, 5-(10-(naphthalen-2-yl) anthracen-9-yl)spiro[benzo[c]fluorene-7,9′-fluorene] (NA-SBFF) and 5-(10-(4-(naphthalen-1-yl)phenyl)anthracen-9-yl)spiro[benzo[c]fluorene-7, 9′-fluorene] (NPA-SBFF), were designed and synthesized via two-step Suzuki coupling reactions. Introduction of a spiro group into the structure of the anthracene moieties lead to a reduction in crystallization tendency, and a high glass transition temperature was observed. Typical blue fluorescent organic light emitting diodes with the configuration of ITO/N,N′-diphenyl-N, N′-bis[4-(phenyl-m-tolyl-amino)phenyl]biphenyl-4,4′-diamine (DNTPD)/N,N′-di(1-naphthyl)-N,N′-diphenylbenzidine (NPB)/HOST: Dopant/tris(8-hydroxyquinoline)aluminum (Alq3)/LiF were developed using SBFF-type anthracene derivatives as a host material and N,N,N′,N′-tetraphenylspiro[benzo[c]fluorene-7,9′-fluorene]-5, 9-diamine (TPA-SBFF) as a dopant material. A device obtained from NA-SBFF doped with TPA-SBFF showed blue color purity of 0.146 and 0.167, a luminance efficiency of 8.65 cd/A, and an external quantum efficiency >6.01% at 8.0 V.
