The object of the present invention is to provide a light-emitting element material containing a pyrene compound represented by the general formula (1), which can form a light-emitting element with high efficiency and excellent durability; and also provide a light-emitting element using the light-emitting element material, Among them, R 1 to R 18 may be the same or different, and are selected from hydrogen, alkyl, cycloalkyl, heterocyclyl, alkenyl, cycloalkenyl, alkynyl, alkoxy, alkylthio, aryl Ether group, arylsulfide group, aryl group, heteroaryl group, halogen atom, carbonyl group, carboxyl group, oxycarbonyl group, carbamoyl group, amino group, phosphine oxide group and silyl group, R 1 to R 18 A ring can be formed between adjacent substituents in , n is an integer from 1 to 3, X is a group selected from -O-, -S- and -NR 19 -, R 19 is a group selected from hydrogen, alkane group, cycloalkyl group, heterocyclyl group, alkenyl group, cycloalkenyl group, alkynyl group, aryl group, heteroaryl group and amino group, R 19 can combine with R 11 or R 18 to form a ring, Y is a single A bond, an arylene group or a heteroarylene group, any n of R 1 to R 10 and any one of R 11 to R 19 are used to connect to Y. |
