Abstract
A spiro-based compound containing cyclopentaphenanthrene and fluorene, which is used for an organoelectroluminescent device and an organoelectroluminescent device having the spiro-based compound. The spiro-based compound containing cyclopentaphenanthrene and fluorene can be easily manufactured to have high solubility, high color purity, and good thermal stability. The spiro-based compound containing cyclopentaphenanthrene and fluorene is suitable as a substance for an organic film, in particular, an emission layer of an organoelectroluminescent device. Further, the spiro-based compound containing cyclopentaphenanthrene and fluorene can be used as an organic dye, or an electron material such as a non-linear optical material.
