ABSTRACT:
Provided are a cyclopentaphenanthrene-based compound and an organic EL device using the same. The cyclopentaphenanthrene-based compound is easy to prepare and excellent in solubility, color purity, and color stability. The cyclopentaphenanthrene-based compound is useful as a material for forming an organic layer, in particular, a light-emitting layer in an organic EL device, and as an organic dye or an electronic material such as a nonlinear optical material.
