Abstract:
1. A naphthalene derivative, represented by a formula (1) as follows, where:Ar n, m and l each represent an integer in a range of 1 to 5; p represents an integer in a range of 0 to 5; when n, m, l and p each are 2 or more, a plurality of Ar when the naphthalene derivative has a structure in which two naphthalene skeletons are consecutively bonded together, the structure of the naphthalene derivative is represented by any one of formulae (1-A), (1-B), (1-C) and (1-D) as follows; the naphthalene skeletons represented by the formulae (1-A), (1-B) and (1-C) each are allowed to have a substituent(s) at any position(s) or allowed to be unsubstituted; in the formula (1-D), R represents a substituent, R being allowed to represent a single substituent or plural substituents, the single or plural substituent(s) being allowed to be in any position(s) of the two naphthalene skeletons, the plural substituents being allowed to be mutually the same or different when R represents the plural substituents; when the naphthalene derivative has a structure in which three naphthalene skeletons are consecutively bonded together, a naphthalene skeleton of the three naphthalene skeletons that is positioned at the center of the structure is tetravalent or more while at least either one of the other naphthalene skeletons of the three naphthalene skeletons that are positioned at ends of the structure is trivalent or more; when the naphthalene derivative has a structure in which four naphthalene skeletons are consecutively bonded together, at least one of the four naphthalene skeletons is tetravalent or more; when the naphthalene derivative contains a plurality of unsubstituted 9-phenanthrenes, the number of the unsubstituted 9-phenanthrenes is 3 or more; and when Ar
