Abstract

Disclosed are a novel amino anthracene derivative and an organic electro-luminescence device using the same. More specifically, the disclosed amino anthracene derivative has a core (e.g., indenoanthracene core) of an anthracene moiety (with a high device characteristic) linked to a fluorene moiety (with a high fluorescence characteristic), in which in the core is substituted with at least one amine group represented by Formula 2 and the disclosed organic electro-luminescence device uses the amino anthracene derivative as a light emitting layer material so as to be enhanced in efficiency, operating voltage, and life span.
