Organic compound, charge-transporting material, composition containing the compound, organic electroluminescent element, display device, and lighting device

An organic compound which is represented by formula (3), has a molecular weight of 750 or more and 2,000 or less, and has one or no carbazolyl group in the molecule:

• wherein
• D represents CH or a nitrogen atom;
• E and F each independently are selected from substituents represented by formulae (4-1) to (4-6):
• —X6 (4-1)
• —Ar16—X7 (4-2)
• —Ar17—Ar18—X8 (4-3)
• —Ar19—Ar20—Ar21—X9 (4-4)
• —Ar22—Ar23—Ar24—Ar25—X10 (4-5)
• —Ar26—Ar27—Ar28—Ar29—Ar30—X11 (4-6)
• wherein Ar16 represents a 1,2-phenylene group or 1,3-phenylene group, which may have a substituent, Ar17 to Ar30 each independently represent a 1,2-phenylene group, 1,3-phenylene group, or 1,4-phenylene group, which may have a substituent, and
• X6 to X11 each independently represent an aromatic hydrocarbon group which may have a substituent, a carbazolyl group which may have a substituent, a dibenzofuranyl group which may have a substituent, or a dibenzothienyl group which may have a substituent,
• with the proviso that E and F each contain at least one of a 1,2-phenylene group and a 1,3-phenylene group;
• L represents a direct bond or a divalent aromatic hydrocarbon group which may have a substituent, and forms a bond with any one of the substitution positions of R1 to R5;
• R1 to R5 each independently represent a bond with L, a hydrogen atom, a phenyl group which may have a substituent, a dibenzofuranyl group which may have a substituent, a dibenzothienyl group which may have a substituent, an alkyl group, a silyl group, a fluorine atom, or a perfluoroalkyl group;
• and R6 to R18 each represent a hydrogen atom, a phenyl group which may have a substituent, a dibenzofuranyl group which may have a substituent, a dibenzothienyl group which may have a substituent, an alkyl group, a silyl group, a fluorine atom, or a perfluoroalkyl group;
• with the proviso that when D is represented by a nitrogen atom, E and F are not the same groups.
