  • Patent number: 10562920
    Abstract: The present invention concerns heterometallic metallacrown compounds incorporating Ga(III) and Ln(III) cations, with a templating ligand such as salicylhydroxamic acid or derivatives thereof, wherein said metallacrown contains at least one repeating [—Ga—N—O—] sub-unit where the N—O derives from the templating ligand.
    Type: Grant
    Filed: April 18, 2016
    Date of Patent: February 18, 2020
    Assignees: THE REGENTS OF THE UNIVERSITY OF MICHIGAN, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE
    Inventors: Evan R. Trivedi, Vincent L. Pecoraro, Svetlana V. Eliseeva, Stépane Petoud, Chun Y. Chow, Tu Ngoc Nguyen, Jacob Charles Lutter, Ivana Martinic
  • Patent number: 10174057
    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.
