Claim:
A dendrimer compound comprising a core unit, a bridge unit, and a dendron unit, wherein the core unit comprises a functional group selected from the group consisting of functional groups represented by Formulas 11 to 15 below: where *** is a binding site with the bridge unit wherein the bridge unit comprises a divalent or trivalent functional group selected from the group consisting of a substituted or unsubstituted C 6 -C 50 aromatic hydrocarbon and a substituted or unsubstituted C 3 -C 50 hetero aromatic hydrocarbon, and wherein the dendron unit comprises a monovalent fluorene-based functional group represented by Formula 1 below: where Z is selected from the group consisting of Ar 1 and Ar 2 are each independently selected from the group consisting of a substituted or unsubstituted C 6 -C 50 aryl group and a substituted or unsubstituted C 3 -C 50 heteroaryl group, X 1 and X 2 are each independently selected from the group consisting of nitrogen (N), boron (B), and phosphorus (P), Y 1 , Y 2 , Y 3 , and Y 4 are each independently selected from the group consisting of a single bond, a substituted or unsubstituted C 1 -C 50 alkylene group, a substituted or unsubstituted C 2 -C 50 alkenylene group, a substituted or unsubstituted C 2 -C 50 alkynylene group, a substituted or unsubstituted C 3 -C 50 cycloalkylene group, a substituted or unsubstituted C 1 -C 50 alkoxylene group, a substituted or unsubstituted C 6 -C 50 arylene group, and a substituted or unsubstituted C 3 -C 50 heteroarylene group, R 1 , R 2 , and R 3 are each independently selected from the group consisting of a hydrogen atom, a heavy hydrogen atom, deuterium, tritium, a halogen atom, a cyano group, an amino group, a nitro group, a hydroxyl group, a carboxyl group, a substituted or unsubstituted C 1 -C 50 alkyl group, a substituted or unsubstituted C 2 -C 50 alkenyl group, a substituted or unsubstituted C 2 -C 50 alkynyl group, a substituted or unsubstituted C 3 -C 50 cycloalkyl group, a substituted or unsubstituted C 1 -C 50 alkoxy group, a substituted or unsubstituted C 6 -C 50 aryl group, and a substituted or unsubstituted C 3 -C 50 heteroaryl group, R′ and R″ are each independently selected from the group consisting of a hydrogen atom, a heavy hydrogen atom, deuterium, tritium, a halogen atom, a cyano group, an amino group, a nitro group, a hydroxyl group, a carboxyl group, a substituted or unsubstituted C 1 -C 50 alkyl group, a substituted or unsubstituted C 6 -C 50 aryl group, and a substituted or unsubstituted C 3 -C 50 heteroaryl group, wherein at least two adjacent groups of R 1 , R 2 , R 3 , R′ and R″ are linked to form a saturated or unsaturated ring, and * is a binding site between the bridge unit and one selected from the group consisting of Ar 1 , Z, and the fluorene group in Formula 1.
