Disclosed is a light-emitting device material containing a pyrene compound represented by the general formula (1) below. This light-emitting device material enables to provide a light-emitting device having high efficiency and excellent durability. Also disclosed is a light-emitting device using such a light-emitting device material. (In the formula (1), R<1>-R<18> independently represent a group selected from a 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 aryl ether group, an aryl thioether 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, and adjacent substituents among R<1>-R<18> may combine together to form a ring; n represents an integer of 1-3; X represents a group selected from -O-, -S- and -NR<19>- wherein R<19> represents a group selected from a hydrogen, an alkyl group, a cycloalkyl group, a heterocyclic group, an alkenyl group, a cycloalkenyl group, an alkynyl group, an aryl group, a heteroaryl group and an amino group, and R<19> may form a ring together with R<11> or R<18>; and Y represents a single bond, an arylene group or a heteroarylene group, and n of R<1>-R<10> and one of R<11>-R<19> are used for linkage with Y. |
