Abstract:
The present invention provides an organic thin film light-emitting element having improved light-emitting efficiency and durable service life. The compound of the present invention has the structure represented by general formula (1) below. In general formula (1), Ar1 is an aromatic group having a specific structure, and Ar2 is a separate aromatic group having a specific structure. n is an integer of 1 or 2, and p is an integer of 1 or 2. However, n+p=3. When n is 2, each Ar1 may be the same or different, and when p is 2, each Ar2 may be the same or different. However, Ar1 and Ar2 are not the same group.
