Polycyclic aromatic hydrocarbon derivative, fluorescent material, phosphorescent material, and light-modulating material

A polycyclic aromatic hydrocarbon derivative that is a derivative of a polycyclic aromatic hydrocarbon having 6 or more aromatic rings and has a substituent represented by a following formula (10):

• [Chemical 4]
• in which R1 and R2 are carbon atoms of the aromatic rings in the polycyclic aromatic hydrocarbon;
• R3 and R4 are carbon atoms of an aromatic ring or a heterocyclic ring in a group having the aromatic ring or the heterocyclic ring;
• R9 and R10 are each a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, an alkoxy group (with an alkyl group having 1 to 20 carbon atoms), a cyano group, a nitro group, an amino group, an acylamino group, an alkylcarbonyl group, an arylcarbonyl group, or an acetoxy group;
• and m is a number of substituents.
