PROBLEM TO BE SOLVED: To provide a compound preparable of an organic electroluminescent element having sufficient emission lifetime with a low driving voltage, a composition for organic electroluminescent elements, and an organic electroluminescent element. SOLUTION: The light-emitting layer of the organic electroluminescent element is formed by using the compound for organic electroluminescent elements comprising the compound represented by formula (I) and an organic solvent by a wet film-forming method (wherein phenyl groups A and B may independently have an optional substituent and express a mutually different structure including the substituent. However, neither one of the phenyl groups A and B forms a part of a condensed ring by condensing with another optional ring). COPYRIGHT: (C)2012,JPO&INPIT |
