Claim:
A trinaphthyl monoamine or a derivative thereof according to any one of formulae (I) to (III): wherein: each of R 1 to R 3 is independently selected from the group consisting of: a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms; a substituted or unsubstituted aryl group having 6 to 50 carbon atoms; a substituted or unsubstituted aralkyl group having 7 to 50 carbon atoms; a substituted or unsubstituted cycloalkyl group having 3 to 50 carbon atoms; a substituted or unsubstituted alkoxyl group having 1 to 50 carbon atoms; a substituted or unsubstituted arylalkenyl group having 8 to 50 carbon atoms; a substituted or unsubstituted aryloxy group having 6 to 50 carbon atoms; a substituted or unsubstituted silyl group having 1 to 20 carbon atoms; a substituted or unsubstituted heterocyclic group having 5 to 50 carbon atoms; and a substituent represented by the structure (A): wherein: each of X 1 to X 3 is independently selected from the group consisting of: a hydrogen atom; a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms; a substituted or unsubstituted aryl group having 6 to 50 carbon atoms; a substituted or unsubstituted cycloalkyl group having 3 to 50 carbon atoms; and a substituted or unsubstituted heterocyclic group having 5 to 50 carbon atoms; a, b, and c each independently represents an integer of 0 to 7; when a is 2 or greater, plural R 1 's may be identical to or different from each other, and adjacent R 1 's are not bonded with each other; when b is 2 or greater, plural R 2 's may be identical to or different from each other, and adjacent R 2 's are not bonded with each other; and when c is 2 or greater, plural R 3 's may be identical to or different from each other, and adjacent R 3 's are not bonded with each other.
