Abstract:
1. A fluorene-based derivative expressed by the following Formula (1): wherein k and n each are an integer of 0 to 10 and satisfy k+n>1; m is an integer of 1 to 10; X and Y each independently represents a single bond, a substituted or unsubstituted aromatic group having 6 to 50 nuclear carbon atoms, a substituted or unsubstituted alkylene group having 1 to 50 carbon atoms or a substituted or unsubstituted alkenylene group having 1 to 50 carbon atoms; and X and Y may be the same with or different from each other; A and C each independently represents a substituted or unsubstituted aromatic group having 6 to 50 nuclear carbon atoms, a substituted or unsubstituted aromatic heterocyclic group having 5 to 50 nuclear atoms, a substituted or unsubstituted alkyl group or alkylene group having 1 to 50 carbon atoms or a substituted or unsubstituted alkenyl or alkenylene group having 1 to 50 carbon atoms; A and C may be the same with or different from each other; however, (a) when X or Y is a single bond, A or C represents a substituted or unsubstituted condensed polycyclic aromatic group having two rings or a substituted or unsubstituted condensed polycyclic heterocyclic group having two rings, and (b) when X and Y are single bonds, both A and C cannot represent an anthrylene group; B represents a single bond, a substituted or unsubstituted aromatic group having 6 to 50 nuclear carbon atoms, a substituted or unsubstituted alkylene group having 1 to 50 carbon atoms or a substituted or unsubstituted alkenylene group having 1 to 50 carbon atoms; FL represents a fluorene-based derivative group represented by any of the following Formulas (2) to (5) or a group comprising the combination of these fluorene-based derivative groups, and when m is 2 or more, a plurality of (FL—B) may be the same with or different from each other; in Formulas (2) to (5), L represents a single bond; Z is a carbon atom; Q is a cyclic structure-forming group, and a cyclic structure formed by Z—Q may further be condensed with a substituted or unsubstituted cycloalkyl group having 1 to 50 carbon atoms, a substituted or unsubstituted aromatic group having 6 to 50 nuclear carbon atoms or a substituted or unsubstituted aromatic heterocyclic group having 5 to 50 nuclear atoms; wherein Ar
