The present technology provides a coating system including a luminophoric material. The luminophoric material is a pyridine-containing ligand chosen from a substituted or unsubstituted bidentate pyridine compound, a substituted or unsubstituted tridentate pyridine compound, or a combination of two or more thereof. Alternatively, the luminophoric material may be a fluorescent dye. The coating system may include a topcoat material, a primer material, or a combination thereof.

A functionalized siloxane includes a ligand capable of coordinating a metal. The functionalized siloxane includes a pyridine-containing ligand attached to a siloxane polymer. The functionalized siloxanes can be employed to provide complexes including a metal that may impart a desired property to the polymer. In one embodiment, the polymer can complex lanthanide metals that are capable of phosphorescing upon exposure to UV irradiation. Such polymers can be employed to provide functional materials such as, for example, luminescent films, coatings, etc.
