<p><P>PROBLEM TO BE SOLVED: To obtain an organic electroluminescent element having excellent luminous efficiency and durability. <P>SOLUTION: The organic electroluminescent element comprises a compound represented by general formula (1) (wherein R<SP POS="POST">C1</SP>-R<SP POS="POST">C16</SP>and R<SP POS="POST">1</SP>-R<SP POS="POST">7</SP>are each independently a hydrogen atom, alkyl which may contain a substituent Z, aryl which may contain a substituent Z, heteroaryl which may contain a substituent Z, alkoxy which may contain a substituent Z, substituent-containing amino, substituent-containing silyl, cyano or fluorine atom; R<SP POS="POST">X</SP>is carbazolyl which may contain a substituent Z, fluorine atom, cyano or perfluoroalkyl; with proviso that when R<SP POS="POST">X</SP>is carbazolyl which may contain a substituent Z, R<SP POS="POST">6</SP>does not represent carbazolyl; substituent Z is alkyl, alkenyl, aryl, heteroaryl, alkoxy, phenoxy, a fluorine atom, silyl, amino, cyano or a group obtained by combining the groups and a plurality of substituents Z may be mutually bonded to form an aryl ring). <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
