A 1,10-phenanthroline derivative capable of sufficiently controlling functions such as oxidation-reduction characteristics and optical characteristics is obtained. The following equation is provided. Embedded image (Wherein NY and NY ′ represent a tertiary amino group, N is a nitrogen atom directly bonded to the third and eighth positions of 1,10-phenanthroline, and NY and NY ′ are the same or different. be able to.) And a chelating ligand comprising the 1,10-phenanthroline derivative and the derivative. [Selection diagram] None |
