Abstract
A novel compound is provided. The novel compound is represented by General Formula (G1). In General Formula (G1), A represents a substituted or unsubstituted condensed aromatic ring having 10 to 30 carbon atoms or a substituted or unsubstituted condensed heteroaromatic ring having 10 to 30 carbon atoms, and R1 represents a substituted or unsubstituted aryl group having 6 to 25 carbon atoms. Each of Y1 and Y2 independently represents a cycloalkyl group having a bridge structure and having 7 to 10 carbon atoms.
Claims15
A compound comprising:
- a fused ring having 10 to 30 carbon atoms;
- a first substituent bonding to the fused ring;
- and
- a second substituent bonding to the fused ring,
- wherein the fused ring is one of an aromatic ring and a heteroaromatic ring,
- wherein each of the first substituent and the second substituent is a diarylamino group,
- wherein the first substituent comprises:
- a first nitrogen atom bonding to the fused ring;
- a first benzene ring bonding to the first nitrogen atom;
- and
- a first cycloalkyl group bonding to the first benzene ring, the first cycloalkyl group comprising a bridge structure and having 7 to 10 carbon atoms, and
- wherein the second substituent comprises:
- a second nitrogen atom bonding to the fused ring;
- a second benzene ring bonding to the second nitrogen atom;
- and
- a second cycloalkyl group bonding to the second benzene ring, the second cycloalkyl group comprising a bridge structure and having 7 to 10 carbon atoms.
