Abstract
An organic compound that is stable in an excited state and has high emission efficiency is provided. An organic compound represented by General Formula (G1) is provided. Note that in General Formula (G1), Qrepresents sulfur or oxygen. Rto Reach independently represent hydrogen, deuterium, a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 10 carbon atoms, a substituted or unsubstituted polycyclic alkyl group having 6 to 10 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms, or a substituted or unsubstituted heteroaryl group having 2 to 30 carbon atoms. In addition, Arepresents an aryl group having 6 to 100 carbon atoms and including a substituted or unsubstituted substituent, or a heteroaryl group having 2 to 100 carbon atoms and including a substituted or unsubstituted substituent. Deuterium is substituted for at least one of hydrogen contained in Rto Rand A.
