ORGANIC ELECTROLUMINESCENT ELEMENT, LIGHT-EMITTING DEVICE USING ORGANIC ELECTROLUMINESCENT ELEMENT, DISPLAY DEVICE USING ORGANIC ELECTROLUMINESCENT ELEMENT, LIGHTING DEVICE USING ORGANIC ELECTROLUMINESCENT ELEMENT, AND COMPOUND FOR ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

An organic electroluminescent element, which comprises a substrate, a pair of electrodes including a positive electrode and a negative electrode that are arranged on the substrate, and an organic layer that is arranged between the electrodes, and wherein the organic layer contains a phosphorescent material and a compound represented by the formula. This organic electroluminescent element has excellent durability and is suppressed in chromaticity shift after storage at high temperatures. (In the formula, X101 represents an oxygen atom or a sulfur atom; each one of R101-R110 represents a hydrogen atom or a substituent (excluding an alkyl group and a cyano group), and the plurality of R108-R110 moieties may be the same as or different from each other, respectively; and L101 represents a single bond or an arylene group.)
