LUMINESCENT COMPOUNDS AND ELECTROLUMINESCENT DEVICE USING THE SAME

The present invention relates to organic electroluminescent compounds and organic electroluminescent devices employing the same. More specifically, the invention relates to organic electroluminescent compounds containing an anthracenyl group or an aryl group having an anthracenyl substituent m the aryl ring of fluorene or indenofluorene, as a blue electroluminescent material in an organic electroluminescent layer. The electroluminescent compounds according to the invention exhibit high luminous efficiency and excellent life property, so that an OLED device having very good operation lifetime can be prepared therefrom.

3D monodisperse oligofluorenes with non-conjugated triphenylamine-based cores: Synthesis and optoelectronic properties

Two 3D monodisperse oligofluorenes with non-conjugated triphenylamine-based cores have been synthesized by Friedel-Crafts copolycondensation reaction. The oligomers, PF3-TPA and PF3-TPA3, consist of three fluorene pentamer arms that are connected non-conjugately through a triphenylamine (TPA) and 1,3,5-tris(triphenylammo)benzene core (TPA 3), respectively, at the 9-position of the central fluorene of the pentafluorene arms. The coplanar structures of the cores and the linkages at the centre of the pentafluorene arms produced a 3D structure of oligomers. This specific structure efficiently retarded the crystallization tendencies of the pentafluorene arms and gave the materials completely amorphous morphological structures. Both oligomers emit deep-blue fluorescence with high efficiencies in thin films (Φpl-film = 67% for PF3-TPA3 and 86% for PF3-TPA). The introduction of triphenylamine units into the core promoted the hole-injection ability while not obviously scarificing the electron-injection ability of the oligomers. The multi-layer devices ITO/PBDOT-PSS/PF3-TPA3 and PF3-TPA/TPBI/LiF/Al were fabricated to investigate the electroluminescence (EL) properties of the two oligomers. Both oligomers showed a low turn-on voltage of 4 V. The luminances reached 1946 cd/m2 at 7.5 V in the PF3-TPA 3 device and 1055 cd/m2 at 8 V in the PF3-TPA device. The EL efficiencies at this luminance were 1.63 and 1.57 cd/A, respectively.

Synthesis and properties of 9,9-diarylfluorene-based triaryldiamines

(matrix presented) 9,9-Diaryl-2,7-dibromofluorene was synthesized by a triflic acid promoted Friedel-Crafts reaction. Introduction of diarylamino groups at its C2 and C7 positions by a Pd-catalyzed amination results in the formation of a novel class of triaryldiamines. The 9,9-diaryl substituents at the central linkage play a less important role in the photophyscial properties but affect the oxidation potential and improve the morphological stability of these new triarylamines.
