Abstract: An electron-injection organic compound with low solubility in water is provided. An organic compound represented by General Formula (G1) is provided. In the organic compound, Ar represents a substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 carbon atoms forming a ring or a substituted or unsubstituted heteroaromatic hydrocarbon group having 2 to 30 carbon atoms forming a ring, each of R1 and R2 independently represents hydrogen (including deuterium), an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted amino group, a substituted or unsubstituted aryl group having 6 to 13 carbon atoms forming a ring, or a substituted or unsubstituted heteroaryl group having 2 to 13 carbon atoms forming a ring, n represents an integer greater than or equal to 1 and less than or equal to 6, and L is the group represented by General Formula (L-1). In General Formula (L-1), each of R3 and R4 independently represents hydrogen (including deuterium) or an alkyl group having 1 to 6 carbon atoms, and k is an integer greater than or equal to 1 and less than or equal to 5.

Abstract: A material for a hole-transport layer includes a monoamine compound. The first aromatic group, the second aromatic group, and the third aromatic group are bonded to the nitrogen atom of the monoamine compound. The first and second aromatic groups each independently include 1 to 3 benzene rings. One or both of the first and second aromatic groups have one or more hydrocarbon groups each having 1 to 12 carbon atoms each forming a bond only by the sp3 hybrid orbitals. The total number of the carbon atoms in the hydrocarbon group in the first or second aromatic group is 6 or more. The total number of the carbon atoms in all of the hydrocarbon groups in the first and second aromatic groups is 8 or more. The third aromatic group is a substituted or unsubstituted monocyclic condensed ring or a substituted or unsubstituted bicyclic or tricyclic condensed ring.

Abstract: A novel heterocyclic compound is provided. A highly efficient and reliable light-emitting element is provided. The heterocyclic compound is represented by a general formula (G1). In the general formula (G1), any one, two, or three of Y1 to Y4 in a ring A represent N atoms, and the rest of Y1 to Y4 represents CH. In the case where any two or three of the Y1 to Y4 are N atoms, the N atoms are not next to each other. Further, Ar1 represents a substituted or unsubstituted biphenyldiyl group, Ar2 represents a substituted or unsubstituted biphenyldiyl group, Cz1 represents a substituted or unsubstituted heterocyclic group including a carbazole skeleton, Cz2 represents a substituted or unsubstituted heterocyclic group including a carbazole skeleton, the carbazole skeleton included in the Cz1 is directly bonded to the Ar1, and the carbazole skeleton included in the Cz2 is directly bonded to the Ar2.
