Abstract
A metallacrown complex has the formula: Ln(III)[12-MC-4]2[24-MC-8], wherein MC is a metallacrown macrocycle with a repeating sub-unit consisting of a transition metal (M(II)) and a hydroxamic acid (HA) ligand that produces a ligand-based charge transfer state when incorporated into the metallacrown complex. In an example of a method for making the metallacrown complex, a hydroxamic acid (HA) ligand that is to produce a ligand-based charge transfer state when incorporated into the metallacrown complex, a transition metal salt, and a rare-earth salt are dissolved in a solvent to form a solution. A base is added to the solution. The solution is stirred at a predetermined temperature for a predetermined time. The solution is exposed to a purification method to produce crystals of the metallacrown complex.
