The present invention can easily form a thin film by a wet method, and a phosphorescent light emitting agent from which an organic electroluminescent device having high luminescence brightness is obtained, a method for producing the same, a luminescent composition containing the phosphorescent light emitting agent, and a light emitting layer containing the phosphorescent light emitting agent An organic electroluminescent device having a light emitting device and a method of manufacturing the same are disclosed.n n n The phosphorescent light emitting agent of the present invention is composed of a polymer material containing a structural unit represented by the following formula (1) in a molecule.n n n <Formula 1>n n n n n n n n In the formula, M is a divalent to tetravalent metal atom, R 1 and R 2 are a hydrogen atom, a halogen atom, an alkyl group, a cycloalkyl group, an aryl group or a heterocyclic group, and may be the same as or different from each other. X 1 is a phenylene group or a carbonyloxy group, X 2 is an alkylene group, L is an organic ligand, p is an integer of 1 to 3, q is O or 1. |
