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