摘要：
A compound represented by the following Formula (1) is useful as an electron transport material of an organic EL device, and an organic EL device comprising the compound in the electron transport layer is long in life, and low in drive voltage: wherein G is an n-valent link, n is an integer of 2 to 4; R1 to R4 are each independently hydrogen, a monovalent group, or a free valency bonded with G, and R5 to R8 are each independently hydrogen or a monovalent group, and one of R1 to R4 is a free valency bonded with G; and n groups of 2,3′-bipyridyl may be the same or different with each other.
