PURPOSE: Provided is an organic electroluminescence compound used as a luminescence layer forming material in an organic electroluminescence device, which has excellent blue light emitting efficiency, good stability and long working life. CONSTITUTION: The organic electroluminescence compound used as a luminescence layer forming material in an organic electroluminescence device is represented by the formula of R1-CX=CY-R2, wherein R1 and R2 are identical or different, and each of them represents a substituted or unsubstituted aryl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted pyridyl group, a substituted or unsubstituted heterocyclic group, or a substituted or unsubstituted vinyl group in which X with R1 or Y with R2 can form an interconnected ring structure; X and Y are identical or different, and each of them represents hydrogen, an alkyl group, an acyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted pyridyl group, a substituted or unsubstituted heterocyclic group, or a substituted or unsubstituted vinyl group, except that both of X and Y are hydrogen. |
