ORGANIC ELECTROLUMINESCENT ELEMENT, COMPOUND AND MATERIAL FOR ORGANIC ELECTROLUMINESCENT ELEMENT, USED IN THE SAME, AND LIGHT EMITTING DEVICE, DISPLAY DEVICE AND ILLUMINATION DEVICE, USING THE ELEMENT

摘要

An organic electroluminescent element comprising a substrate, a pair of electrodes including an anode and a cathode, disposed on the substrate, and at least one organic layer which is arranged between the electrodes and which includes a light emitting layer, wherein the organic layer contains a compound represented by general formula (1) in at least one layer. The organic electroluminescent element has a high luminous efficiency, excellent blue color purity, and little chromaticity change due to drive deterioration. (In the formula, the two Xs either both represent an O atom or both represent an S atom, and R1-R10 each independently represents a hydrogen atom or a substituent group).

1. An organic electroluminescent element, comprising:
a substrate; a pair of electrodes including an anode and a cathode, disposed on the substrate; and at least one organic layer which is arranged between the electrodes and which includes a light emitting layer; wherein the organic layer contains a compound expressed by general formula (1) in at least one layer: wherein in general formula (1), the two X's represent the same linking group, and either both represent oxygen atoms or both represent sulfur atoms, R1 through R10 independently represent a hydrogen atom or a substitution group, and R1 through R10 may jointly form a ring. However, if the two X's represent sulfur atoms, at least one of R2, R3, R5, and R6 represents a substitution group.
