Fluorene derivative, light-emitting element, light-emitting device, electronic device, and lighting device

A light-emitting device comprising a light-emitting element, the light-emitting element comprising:

• a pair of electrodes;
• and
• an electroluminescence layer including a fluorene derivative between the pair of electrodes,
• wherein:
• the fluorene derivative is represented by a general formula (G1);
• R1 to R8 independently represent any one of a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, and a substituted or unsubstituted biphenyl group;
• α1 to α4 independently represent any of a substituted or unsubstituted arylene group having 6 to 12 carbon atoms;
• Ar1 and Ar2 independently represent any of an aryl group having 6 to 13 carbon atoms in a ring and Ar3 represents any of an alkyl group having 1 to 6 carbon atoms and a substituted or unsubstituted aryl group having 6 to 12 carbon atoms;
• and
• J, k, m, and n independently represent 0 or 1, and at least one of J and k is 1.
