Compound and organic light-emission device

A compound represented by Chemical Formula 1:

• wherein, in the Chemical Formula 1, each of R1 to R4 independently represents one selected from a group consisting of hydrogen, deuterium, halogen, a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C2 to C60 heteroaryl group, a substituted or unsubstituted C3 to C30 cycloalkyl group, a C1 to C30 alkoxy group and a C6 to C30 aryloxy group;
• each of a and b independently denotes an integer of 0 to 4, wherein when a or b denotes an integer of 2 or greater,—each R1 is the same or different and each R2 is the same or different,
• each of c and d independently denotes an integer of 0 to 4, wherein when c or d denotes an integer of 2 or greater, each R3 is the same or different and each R4 is the same or different,
• each of m and n independently denotes an integer of 0 to 4, wherein when m or n denotes an integer of 2 or greater, each A is the same or different and each B is the same or different,
• each of o and p independently denotes an integer of 0 to 4, wherein when o or p denotes an integer of 2 or greater, each C is the same or different and each D is the same or different,
