Abstract
An anthracene derivative represented by the general formula (G1) is provided. The anthracene derivative represented by the general formula (G1) is a novel anthracene derivative having a wide band gap. Further, the anthracene derivative has a large energy gap and can be very suitably used as a material for a light-emitting element which exhibits blue light emission.
Claims14
An anthracene derivative comprising:
- an anthracene skeleton comprising a first aryl group and a second aryl group;
- and one triarylamine skeleton comprising a third aryl group and a fourth aryl group, wherein the anthracene skeleton is substituted with the one triarylamine skeleton at a 2-position, wherein the anthracene skeleton is substituted with hydrogen at a 6-position, wherein an arylene skeleton included in the triarylamine skeleton is one selected from group consisting of a substituted and unsubstituted arylene groups having 6 to 13 carbon atoms in a ring system, and wherein each of the third aryl group and the fourth aryl group is unsubstituted phenyl group, and wherein each of the third aryl group and the fourth aryl group is a terminal aryl group of the triarylamine skeleton and wherein each of the first aryl group and the second aryl group is directly bonded to the anthracene skeleton.
