Abstract
A novel dibenzocarbazole compound with which a light-emitting element having low power consumption, high reliability, and high color purity can be fabricated is provided. In the dibenzocarbazole compound, an aryl group which has 14 to 30 carbon atoms and at least an anthracene skeleton is bonded to nitrogen of a dibenzo[a,g]carbazole skeleton or a dibenzo[a,i]carbazole skeleton. Furthermore, a light-emitting element including the dibenzocarbazole compound is provided.
Claims29
A dibenzocarbazole compound,
- wherein an aryl group is bonded to a dibenzo[a,g]carbazole skeleton or a dibenzo[a,i] carbazole skeleton,
- wherein the aryl group is an aryl group which has 14 to 30 carbon atoms and at least an anthracene skeleton, and
- wherein the aryl group is bonded to a 7-position of the dibenzo[a,g]carbazole skeleton or a 11-position of the dibenzo[a,i]carbazole skeleton.
A dibenzocarbazole compound represented by General Formula (G1):
- wherein R11 to R22 each independently represent any of hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 6 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms;
- and Ar represents a substituted or unsubstituted aryl group which has 14 to 30 carbon atoms and at least an anthracene skeleton.
A dibenzocarbazole compound represented by General Formula (G6):
- wherein R31 to R42 each independently represent any of hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 6 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms;
- and Ar represents a substituted or unsubstituted aryl group which has 14 to 30 carbon atoms and at least an anthracene skeleton.
