Low Energy Bioimaging through Molecular Up-Conversion Emission with Imidazolium- and Benzenetriol-Based Er(III) Complexes

New water-soluble imidazolium-based and benzenetriol-based ligands and their 3:2 ligand-to-lanthanide sandwich-type complexes, [Ln2(L1)3H2O], [Ln2(L2)3H2O], and [Ln2(L3)3H2O] (Ln = Er(III), Gd(III), and Lu(III)), were isolated. Upon 980 nm excitation, the Er(III) complexes exhibited metal-centered up-conversion emission in the solid state and in aqueous solution. When incubated in HeLa cells, the complexes appear to localize in the mitochondria, and red and green Er(III)-centered up-conversion emission was observed.

Uranyl Naphthylsalophen and Pyrasal Complexes: Oxo Ligands Acting as Hydrogen Bond Acceptors in the Solid State

Uranium is most stable when it is exposed to oxygen or water in its +6 oxidation state as the uranyl (UO22+) ion. This ion is subsequently particularly stable and very resistant to functionalization d...
