Claim:
A dimethylenecyclohexane compound represented by Formula 1: where R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 are each independently a hydrogen atom, a halogen atom, a cyano group, a hydroxyl group, an amino group, a substituted or unsubstituted C 1 -C 20 alkyl group, a substituted or unsubstituted C 1 -C 20 alkoxy group, a substituted or unsubstituted C 6 -C 30 aryl group, a substituted or unsubstituted C 2 -C 30 heteroaryl group or a substituted amino group represented by —N(Z′)(Z″) where Z′ and Z″ are each independently a substituted or unsubstituted C 1 -C 20 alkyl group, a substituted or unsubstituted C 6 -C 30 aryl group, a substituted or unsubstituted C 2 -C 30 heteroaryl group, a substituted or unsubstituted C 5 -C 20 cycloalkyl group, or a substituted or unsubstituted C 5 -C 30 heterocycloalkyl group; each of X 1 and X 2 is independently a single bond, a double bond, a substituted or unsubstituted C 1 -C 20 alkylene group, a substituted or unsubstituted C 2 -C 20 alkenylene group, a substituted or unsubstituted C 2 -C 20 alkynylene group, a substituted or unsubstituted C 1 -C 20 heteroalkylene group, a substituted or unsubstituted C 7 -C 30 alkylenearylene group, a substituted or unsubstituted C 6 -C 30 arylene group, or a substituted or unsubstituted C 2 -C 30 heteroarylene group; n 1 and n 2 are each independently an integer in the range of 0 to 5, and when n 1 or n 2 is 2 or greater, the X 1 s or X 2 s can be respectively identical or different; Ar 1 and Ar 2 are each independently a substituted or unsubstituted C 6 -C 30 aryl group, a substituted or unsubstituted C 2 -C 30 heteroaryl group, a substituted or unsubstituted C 4 -C 30 cycloalkyl group or a substituted or unsubstituted C 2 -C 30 cycloheteroalkyl group; and at least one of Ar 1 and Ar 2 includes at least two substituents, the substituents included in Ar 1 or Ar 2 are each independently a substituted or unsubstituted C 6 -C 30 aryl group, a substituted or unsubstituted C 2 -C 30 heteroaryl group, a substituted or unsubstituted C 5 -C 20 cycloalkyl group, a substituted or unsubstituted C 5 -C 30 heterocycloalkyl group, or a substituted amino group represented by —N(R′)(R″), where R′ and R″ are each independently a hydrogen atom, a substituted or unsubstituted C 1 -C 20 alkyl group, a substituted or unsubstituted C 6 -C 30 aryl group, a substituted or unsubstituted C 2 -C 30 heteroaryl group, a C 5 -C 20 cycloalkyl group, or a C 5 -C 30 heterocycloalkyl group.
