An object is to provide a new fluorene derivative as a good light-emitting material for organic EL elements. A fluorene derivative represented by General Formula (G1) is provided.
In the formula, R1 to R8 separately represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, or a substituted or unsubstituted biphenyl group. Further, α1 to α4 separately represent a substituted or unsubstituted phenylene group. Ar1 represents a substituted or unsubstituted condensed aromatic hydrocarbon having 14 to 18 carbon atoms forming a ring. Ar2 represents a substituted or unsubstituted aryl group having 6 to 13 carbon atoms forming a ring. Ar3 represents an alkyl group having 1 to 6 carbon atoms or a substituted or unsubstituted aryl group having 6 to 12 carbon atoms. Further, j, m, and n separately represent 0 or 1, and p represents 1 or 2.
本发明旨在提供一种新的芴衍生物,作为有机EL元件的良好发光材料。提供了一种由通式(G1)表示的芴衍生物。在该式中,R1至R8分别表示氢原子,具有1至6个碳原子的烷基,取代或未取代的苯基,或取代或未取代的联苯基。此外,α1至α4分别表示取代或未取代的苯基。Ar1表示形成环的具有14至18个碳原子的取代或未取代的紧缩芳香烃。Ar2表示形成环的具有6至13个碳原子的取代或未取代的芳基。Ar3表示具有1至6个碳原子的烷基或具有6至12个碳原子的取代或未取代的芳基。此外,j,m和n分别表示0或1,p表示1或2。
