Abstract
Official abstract text for this publication.
A light-emitting element having good characteristics can be obtained by using a bipyridine compound having at least one 2,2′-bipyridine structure and at least two anthracene skeletons as light-emitting element materials. In particular, a bipyridine compound in which an anthracene skeleton is bonded to each of the 5-position and the 6-position of 2,2′-bipyridine through an arylene group can be synthesized and a light-emitting element having good characteristics can be obtained in the case where the bipyridine compound is used as a light-emitting element material.
First claim
Opening claim text (preview).
What is claimed is: 1. A compound represented by a formula (G1), wherein R 1 to R 6 , R 10 to R 17 , and R 20 to R 27 each independently represent hydrogen or an alkyl group having 1 to 4 carbon atoms, wherein Ar 1 and Ar 2 each independently represent an arylene group having 6 to 13 carbon atoms, and wherein R 30 and R 40 each independently represen…
