Perylene derivative synthesis process, perylene derivative and organic el device

Abstract

The invention aims to provide a perylene derivative preparation process featuring satisfactory yields and improved preparation efficiency, a perylene derivative obtained by the process, and an organic EL device using the same. The object is achieved by a perylene derivative preparation process comprising subjecting to coupling reaction a 1,8-dihalogenated naphthalene derivative of the formula (1): wherein X is Cl, Br or I, Rto R, Rand Reach are hydrogen, alkyl, alkoxy, alkylthio, alkenyl, alkenyloxy, alkenylthio, aralkyl, aralkyloxy, aralkylthio, aryl, aryloxy, and arylthio radicals which may be substituted, amino radical, cyano radical, hydroxyl radical, —COOMradical (wherein Mis hydrogen, alkyl, alkenyl, aralkyl or aryl), —COMradical (wherein Mis hydrogen, alkyl, alkenyl, aralkyl, aryl or amino), or —OCOMradical (wherein Mis alkyl, alkenyl, aralkyl or aryl), and at least two adjoining radicals selected from among Rto R, Rand Rmay bond or fuse together to form a substituted or unsubstituted carbocyclic aliphatic ring, aromatic ring or fused aromatic ring with the carbon atoms on which they substitute, with the proviso that when the carbocyclic aliphatic ring, aromatic ring or fused aromatic ring has substituent radicals, the substituent radicals are the same as Rto R, Rand R, to thereby synthesize a perylene derivative of the formula (2): wherein R' to R′, R′ and R′ are as defined for Rto R, Rand Rin formula (1), and Rto R, Rand Rand R′ to R′, R′ and R′ may be the same or different.
