| abstract |
In 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 Z1 to Z3 each independently have a structure represented by formula (Z-1) or (Z-2). In formula (Z-1), X1 and X2 each independently represent any one of an alkyl group having 3 to 10 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 10 carbon atoms, a cycloalkyl group having a bridge structure and having 7 to 10 carbon atoms, and a trialkylsilyl group having 3 to 12 carbon atoms. In addition, Ar1 to Ar4 each independently represent a substituted or unsubstituted aromatic hydrocarbon group having 6 to 13 carbon atoms, and at least one of Ar1 to Ar4 has the same substituent as X1 or X2. |
