Abstract
The present invention is related to a cyclopentaphenanthrene-based compound and an organic electroluminescence device using the same. In particular, the cyclopentaphenanthrene-based compound offers several advantages, including easy processibility, high solubility, superior color purity, color stability and thermal stability. Moreover, the cyclopentaphenanthrene-based compound may be used not only as a material for forming an organic layer of an organic electroluminescence device, particularly, a light-emitting layer, but also as a material of an organic pigment or nonlinear optical substance.
