Title:
ORGANIC ELECTROLUMINESCENCE ELEMENT AND MATERIAL
Document Type and Number:
Japanese Patent JP2019073489
Kind Code:
A
Abstract:
To provide a light-emitting material exhibiting a low drive voltage, high current efficiency and high solubility with an organic solvent and less likely causing crystallization of a compound when the material is dissolved in an organic solvent and stored for a long period of time, and an organic electroluminescence element using the light-emitting material.SOLUTION: The present invention discloses a compound represented by a formula (I), an organic electroluminescence element using the above compound as a light-emitting material, and a display element and an illumination device including the organic electroluminescence element. In the formula (I), X1 represents -O-, -SO2-, -CO-, -S-, -CRX1RX2-, -SiRX1RX2-, -NRX3-, or the like, where RX1, RX2, RX3 each independently represent H or a substituted/unsubstituted organic group, and RX1 and RX2 may be coupled to form a group including a cyclic structure; and L11 to L15 and L21 to L25 represent H or a substituent, where at least one in L11 to L15 is an electron-accepting group and at least one in L21 to L25 is an electron-donating group.SELECTED DRAWING: None
