Coatings and methods of using and producing the same are provided. In an exemplary embodiment, a coating includes a first ligand and a second ligand different than the first ligand. The first ligand includes a first carboxylic moiety, a first aromatic moiety, and a first linking moiety connecting the first carboxylic moiety to the first aromatic moiety. the first linking moiety includes an alkene. The second ligand includes a second carboxylic moiety. The coating includes a metal that is a lanthanoid metal, and the coating includes a coating resin.

Coatings and methods for using and producing the same

A method is provided for separating mixtures of different rare earth metals using a ligand having a size-sensitive molecular aperture. The present invention meets the needs in the field by providing method of separating and purifying rare earth metals. The object of this invention is to separate and purify rare earth metals, e.g., the more valuable Dy away from Nd, in mixtures containing such metals using a simple chemical process without the need for countercurrent liquid-liquid separations.
