| abstract |
The present invention relates to a light emitting device material containing a pyrene compound represented by the general formula (1):n nwherein R 1 to R 18 may be the same or different and represent a group selected from hydrogen, an alkyl group, a cycloalkyl group, a heterocyclic group, an alkenyl group, a cycloalkenyl group, an alkynyl group, an alkoxy group, an alkylthio group, an arylether group, an arylthioether group, an aryl group, a heteroaryl group, a halogen, a carbonyl group, a carboxyl group, an oxycarbonyl group, a carbamoyl group, an amino group, a phosphine oxide group and a silyl group; adjacent substituents among R 1 to R 18 may be combined with each other to form a ring; n represents an integer of 1 to 3; X represents -O-; Y represents an arylene group or a heteroarylene group; and n substituents among R 1 to R 10 and any one of R 11 to R 19 are used for linkage with Y. |
