Claim:
A compound as represented by Chemical Formula 1: in Chemical Formula 1, m is an integer of 1 to 7; R 1 is a C4-C10 cycloalkyl group substituted with at least one group selected from the group consisting of hydrogen, deuterium, a halogen group, a nitrile group, an acetylene group, an amine group, an amide group, an ester group, a ketone group, a C1-C20 alkyl group, a C6-C20 cycloalkyl group, a C2-C20 alkenyl group, a C6-C20 aryl group, a silyl group, a C7-C20 alkylaryl group, a C7-C20 arylalkyl group and a C4-C20 heterocyclic group; a C2-C9 heterocyclic group with a heteroatom of O, N or S, substituted with at least one group selected from the group consisting of hydrogen, deuterium, a halogen group, a nitrile group, an acetylene group, an amine group, an amide group, an ester group, a ketone group, a C1-C20 alkyl group, a C6-C20 cycloalkyl group, a C2-C20 alkenyl group, a C6-C20 aryl group, a silyl group, a C7-C20 alkylaryl group, a C7-C20 arylalkyl group, and a C4-C20 heterocyclic group; a C6-C10 aryl group substituted with at least one group selected from the group consisting of hydrogen, deuterium, a halogen group, a nitrile group, an acetylene group, an amine group, an amide group, an ester group, a ketone group, a C1-C20 alkyl group, a C6-C20 cycloalkyl group, a C2-C20 alkenyl group, a C6-C20 aryl group, a silyl group, a C7-C20 alkylaryl group, a C7-C20 arylalkyl group, and a C4-C20 heterocyclic group; or a C5-C10 heteroaryl group with a heteroatom of O, N or S, substituted with at least one group selected from the group consisting of hydrogen, deuterium, a halogen group, a nitrile group, an acetylene group, an amine group, an amide group, an ester group, a ketone group, a C1-C20 alkyl group, a C6-C20 cycloalkyl group, a C2-C20 alkenyl group, a C6-C20 aryl group, a silyl group, a C7-C20 alkylaryl group, a C7-C20 arylalkyl group, and a C4-C20 heterocyclic group, wherein when the R 1 is substituted with at least two groups, the groups that are adjacent to each other can form an aliphatic or aromatic condensed ring; R 2 s are the same with or different from each other, and are independently selected from the group consisting of hydrogen, deuterium, a halogen group, a nitrile group, an acetylene group, an amine group, an amide group, an ester group, a ketone group, a C1-C20 alkyl group, a C2-C20 alkenyl group, a C6-C20 aryl group, a C4-C20 heterocyclic group, a C1-C20 alkoxy group, and a C6-C20 aryloxy group, respectively, and at least two of the R 2 can be linked to each other to form an aliphatic or aromatic ring.
