Abstract
To provide a novel organic compound.SOLUTION: An organic compound is represented by the following General Formula (G1). In General Formula (G1), one of A and B is a group expressed by the following General Formula (g1). The other of A and B, R1 to R8, and R11 to R14 independently represent any of hydrogen, an alkyl group with 1 to 6 carbons, a cyclic hydrocarbon group with 3 to 6 carbons, an alkoxy group with 1 to 6 carbons, a cyano group, a halogen, a haloalkyl group with 1 to 6 carbons, and a substituted or non-substituted aromatic hydrocarbon group with 6 to 60 carbons. R9 and R10 represent any of a cyclic hydrocarbon group, an alkoxy group, a cyano group, a halogen, a haloalkyl group, and a substituted or non-substituted phenyl group.SELECTED DRAWING: Figure 1
