CHARGE TRANSPORT MATERIAL, OGANIC ELECTROLUMINESCENT ELEMENT, AND ILLUMINATION DEVICE, DISPLAY DEVICE, OR LIGHT-EMITTING DEVICE CHARACTERIZED BY USING SAID ELEMENT

摘要

[This] charge transport material which comprises a compound expressed by the following formula has a high efficiency and drive durability after high-temperature storage and resists the occurrence of dark spots (X101 represents a sulfur atom or an oxygen atom; R101 and R102 represent each independently an alkyl group, an aryl group, a heteroaryl group, a fluorine atom, or a silyl group, and may further be substituted with these groups; n101 represents an integer from 0 to 11; n102 represents an integer from 0 to 7; a plurality of R101 and R102 [groups] may be the same or different; and L101 represents a single bond or a divalent linking group; however, one of R101, L101, and R102 includes a fluorine atom, a fluoroalkyl group, a cycloalkyl group, a cycloalkylene group, a silyl group, an alkylsilyl group, an arylsilyl group, or a silicon atom linking group.);
