A light emitting device material containing a pyrene compound of formula (1) and a light emitting device. In formula (1), R1 to R18 are the same or different and are selected from hydrogen, alkyl, cycloalkyl, heterocyclic, alkenyl, cycloalkenyl, alkynyl, alkoxy, alkylthio, arylether, arylthioether, aryl, heteroaryl, halogen, carbonyl, carboxyl, oxycarbonyl, carbamoyl, amino, phosphine oxide and silyl; adjacent substituents among R1 to R18 may be combined with each other to form a ring; n represents an integer of 1 to 3; X is -O-, -S- or -NR19-; R19 is selected from hydrogen, alkyl, cycloalkyl, heterocyclic, alkenyl, cycloalkenyl, alkynyl, aryl, heteroaryl or amino; R19 may be combined with R11 or R18 to form a ring; Y is a single bond, arylene or heteroarylene; and n substituents among R1 to R10 and any one of R11 to R19 are used for linkage with Y |
