摘要
Provided are a phosphorescent material which is excellent in horizontal orientation and the like when a thin film is formed, a process for efficiently producing the phosphorescent material, and a light emitting element using the phosphorescent material. The present invention provides a phosphorescent material represented by the following general formula (1), a process for producing the phosphorescent material, and a light emitting element using the phosphorescent material, wherein the phosphorescent material has a straight-chain conjugated structure, a 2-phenylpyridine ligand, a central metal and a beta-diketone-type ligand, In the general formula (1), end substituents R1 and R2 each is a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, or the like, substituents a to l and o to s each is a hydrogen atom or the like, the central metal M is platinum or the like, and repetition numbers m and n each is an integer of 0 to 4.
