Abstract
The present invention provides an organic light emitting device comprising a first electrode, at least one organic layer and a second electrode, laminated successively, in which at least one layer of the organic layer has a polycyclic aromatic hydrocarbon as a core and comprises at least one of a derivative in which a substituted or unsubstituted Ccycloalkane, or a substituted or unsubstituted Cpolycycloalkane is directly fused to the core or fused to a substituent of the core; and a new organic compound usable in the organic light emitting device. Furthermore, the present invention provides a charge carrier extracting, injecting or transporting material which has a polycyclic aromatic hydrocarbon as a core and comprises a derivative in which a substituted or unsubstituted Ccycloalkane, or a substituted or unsubstituted Cpolycycloalkane is directly fused to the core or fused to a substituent of the core.
