Abstract:
A novel organic compound having an emission spectrum peak at a wavelength longer than 850 nm and an absorption spectrum peak at a wavelength longer than 600 nm is provided. The organic compound is represented by General Formula (G1).
In General Formula (G1), Ar1 to Ar4 each independently represent an aryl group having 6 to 13 carbon atoms in a ring. R1 to R8 each independently represent anyone of hydrogen, an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms, an aryl group having 6 to 13 carbon atoms in a ring, and a heteroaryl group having 3 to 13 carbon atoms in a ring. Q1 and Q2 each independently represent a group having a carbazole skeleton or a group having a triarylamine skeleton and having 18 to 30 carbon atoms in a ring. Furthermore, m and n each independently represent 0 or 1.
