Abstract
A novel organic compound represented by General Formula (G1) is provided. In General Formula (G1), Xand Xeach independently represent a secondary or tertiary alkyl group having 3 to 6 carbon atoms and having a branched carbon atom which is bonded to a phenyl group. In addition, Arrepresents a substituted or unsubstituted condensed aromatic ring skeleton having 10 to 60 carbon atoms and composed of two or more rings or a substituted or unsubstituted condensed heteroaromatic ring skeleton having 8 to 60 carbon atoms and composed of two or more rings. Furthermore, Arrepresents a substituted or unsubstituted aryl group having 6 to 25 carbon atoms. Moreover, n represents any of 1 to 3, and in the case where n is 2 or more, two or more groups bonded to Armay be identical or different.
