Charge transport material, organic electroluminescent element, and illumination device, display device, or light-emitting device characterized by using said element

A charge transport material comprising a compound expressed by General Formula 2 below:

• wherein:
• X111 represents a sulfur atom or an oxygen atom;
• R111, R112, and R113 each independently represent an alkyl group, an aryl group selected from the group consisting of phenyl, naphthyl, and phenanthryl, a heteroaryl group, a fluorine atom, or a silyl group, and may further be substituted with an alkyl group, an aryl group, a heteroaryl group, a fluorine atom, or a silyl group;
• n111 represents an integer from 0 to 11;
• n112 represents an integer from 0 to 2;
• n113 represents an integer from 0 to 4;
• a plurality of R111, R112 and R113 groups may be the same or different;
• AA1 to AA5 each independently represent CH, CR113, or a nitrogen atom;
• m111 represents an integer from 2 to 6;
• however, one of R111, R112, or R113 includes a fluorine atom, a fluoroalkyl group, a cycloalkyl group, a silyl group, an alkylsilyl group, or an arylsilyl group;
• and
• n111, n112, and n113 are not 0 at the same time;
• with the proviso that when AA1 to AA5 each represent CH and m111 represents 2 or 3;
• then one of R111, R112, or R113 is present and includes a silyl group, an alkylsilyl group, an arylsilyl group, or a silicon atom linking group.
