Abstract:
A material for an organic electroluminescent element contains a compound represented by Formula (1): where R1 to R3 independently represent a group such as a deuterium atom and a halogen atom; at least one of R1 to R3 is a group represented by Formula (2); if pluralities of R1 to R3 are present, these substituents may be the same or different or may be bonded to each other to form a ring; n1 represents an integer of 0 to 8; n2 represents an integer of 0 to 3; n3 represents an integer of 0 to 4; n1+n2+n3 is 1 or more; Cbz represents a carbazolyl group; X represents an oxygen atom or a sulfur atom; and L1 represents a single bond or a divalent linking group.
