Simultaneous Enhancement of Near-Infrared Emission and Dye Photodegradation in a Racemic Aspartic Acid Compound via Metal-Ion Modification.

ABSTRACT: Changing functionalities of materials using simple methods is an active area of research, as it is "green" and lowers the developing cost of new products for the enterprises. A new small molecule racemic N,N-dimethyl aspartic acid has been prepared. Its structure is determined by single-crystal X-ray diffraction. It is characterized by FTIR, XPS, ¹H NMR, and mass spectroscopy. Its near-infrared luminescence can be enhanced by the combination of metal ions, including Dy³⁺, Gd³⁺, Nd³⁺, Er³⁺, Sr³⁺, Y³⁺, Zn²⁺, Zr⁴⁺, Ho³⁺, Yb³⁺, La³⁺, Pr⁶⁺/Pr³⁺, and Sm³⁺ ions.
