In addition, the compound of Formula 1 according to the present invention may exhibit excellent light-emitting characteristics as a linking group is modified, and thus may also be usefully applied as a material for the light-emitting layer of the organic electroluminescence device.

(5) That is, the compound of Formula 1 according to the present invention may enhance phosphorescent characteristics of the organic electroluminescence device, and simultaneously, enhance hole injection/transport capabilities, light-emitting efficiency, driving voltage, lifespan characteristics, and the like thereof. Furthermore, according to the kind of substituent group (substitution product) to be introduced, electron transport capabilities may also be enhanced. Therefore, the compound of Formula 1 according to the present invention may be used as a material for an organic material layer, preferably a material for a light-emitting layer (a blue, green and/or red phosphorescent host material), a material for a hole transporting layer, and a material for a hole injection layer, of the organic electroluminescence device.

(6) Specifically, various substituent group (substitution products), particularly, an aryl group and/or a heteroaryl group, are introduced into the compound represented by Formula 1 according to the present invention to significantly increase the molecular weight of the compound and enhance the glass transition temperature, and accordingly, the compound represented by Formula 1 may have thermal stability higher than that of the existing light-emitting material (for example, CBP). Therefore, an organic electroluminescence device including the compound of Formula 1 according to the present invention may be greatly enhanced in terms of performance and lifespan characteristics. The organic electroluminescence device with performance and lifespan characteristics enhanced as described above may resultantly maximize performance of a full-color organic light-emitting panel.

(9) Further, in consideration of performance and lifespan characteristics of the organic electroluminescence device, in the compound of Formula 1 according to the present invention, it is preferred that what does not form a fused ring in Y.sub.1 to Y.sub.4 is CR.sub.3 (for example, when Y.sub.1 and Y.sub.2 forms a fused ring, both Y.sub.3 and Y.sub.4 are CR.sub.3), and what does not form a fused ring in Y.sub.5 to Y.sub.8 is CR.sub.4 (for example, when Y.sub.5 and Y.sub.6 forms a fused ring, both Y.sub.7 and Y.sub.8 are CR.sub.4). In this case, R.sub.3 and R.sub.4 may be the same as or different from each other.

(541) First, a glass substrate thinly coated with indium tin oxide (ITO) to have a thickness of 1,500 Å was ultrasonically washed with distilled water. When the washing with distilled water was completed, the substrate was ultrasonically washed with a solvent such as isopropyl alcohol, acetone, and methanol, dried, transferred to a UV ozone cleaner (Power sonic 405, manufactured by Hwashin Tech), washed for 5 minutes by using UV, and then transferred to a vacuum evaporator.

(542) An organic electroluminescence device was manufactured by stacking m-MTDATA (60 nm)/TCTA (80 nm)/each compound of Synthesis Examples 1 to 85+10% Ir(ppy).sub.3 (300 nm)/BCP (10 nm)/Alq.sub.3 (30 nm)/LiF (1 nm)/Al (200 nm) in this order on the thus prepared ITO transparent substrate (electrode).

Comparative Example

(543) A green organic electroluminescence device was manufactured by the same procedure as in Example 1, except that when a light-emitting layer is formed, CBP was used as a light-emitting host material instead of the compound of Synthesis Example 1.

(544) The structures of m-MTDATA, TCTA, Ir(ppy).sub.3, CBP, and BCP used in Examples 1 to 85 and the Comparative Example are as follows.
