METALLACROWN COMPLEXES AND METHODS OF MAKING THE SAME

, 2015
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 ...

When Molecules Meet in Water-Recent Contributions of Supramolecular Chemistry to the Understanding of Molecular Recognition Processes in Water. [PDF]

ChemistryOpen, 2022
To bind or not to bind? Molecular recognition processes in water are mediated and often even strengthened by the solvent. This review outlines important aspects of these solvent effects and gives an overview of recent progress in the development of synthetic receptors that work in water.

Enabling Visible Light Sensitization of Yb^III, Nd^III and Er^III in Dimeric Ln^III/Ga^III Metallacrowns through Functionalization with Ru^II Complexes for NIR-II Multiplex Imaging. [PDF]

Angew Chem Int Ed Engl
LnRu‐3 dimeric LnIII/GaIII metallacrows bearing four RuII chromophoric complexes have been synthesized and proved to exhibit characteristic emissions of YbIII, NdIII and ErIII in the NIR‐II region upon excitation with visible light through metal‐to‐ligand charge transfer (MLCT) states.

Anionic Boraza‐Crown Ethers

European Journal of Inorganic Chemistry, Volume 26, Issue 26, September 13, 2023., 2023
Making one out of two: Dioxazaborocanes dimerize in the presence of alkoxides to form boraza‐crown ethers. These anionic heterocycles exist in the solid state as well in solution and can coordinate two metal ions per crown ether. Furthermore, they are suitable substrates for cross‐coupling reactions and engage in Suzuki‐Miyaura reactions as proven for ...

Lower Energy Excitation of Water Soluble Near‐Infrared Emitting Mixed‐Ligand Metallacrowns

Chemistry – A European Journal, Volume 29, Issue 29, May 22, 2023., 2023
The best of both worlds: Water solubility of Zn16Ln(pyzHA)16 (H2pyzHA: pyrazine hydroxamic acid) or lower energy excitation of Zn16Ln(quinoHA)16 (H2quinoHA: quinoxaline hydroxamic acid) metallacrowns (MCs)? No need to choose! In water soluble mixed‐ligand Zn16Yb(pyzHA)x(quinoHA)16–x MCs characteristic emission of YbIII in the near‐infrared range can be
