The invention provides an organic luminous compound with a structure as shown in a formula (I) which is described in the specification. According to the invention, a benzimidazole compound is introduced into the mother nucleus of anthracene, and the positions and amount of linking groups are changed so as to improve the electron mobility of the luminous compound; and when used as an electron transport layer material for an organic electroluminescent device, the luminous compound has substantially improved luminous efficiency and life compared with other electron transport layer materials. Theorganic luminous compound uses easily available raw materials and is short in synthesis route, simple in process, low in cost and suitable for industrial production.

A compound represented by the formula (1):wherein G represents a n-valent linker group; n represents an integer of 2 to 4; R1 to R4 independently represent a hydrogen, a univalent group or a free atomic valency binding to the group G; and R5 to R8 independently represent a hydrogen or a univalent group; provided that any one of R1 to R4 is a free atomic valency binding to the group G, and n's 2,3'-bipyridyl groups may be the same as or different from one another. The compound is useful as an electron transporting material for an organic electroluminescent device. An organic electroluminescent device having the compound in the electron transporting layer shows a long operating life and a low driving voltage.
