Speciation of Lanthanide Metal Ion Dopants in Microcrystalline All-Inorganic Halide Perovskite CsPbCl3

David Lyndon Emsley, Dominik Józef Kubicki, Daniel Prochowicz, Amita Ummadisingu, Albert Hofstetter

Lanthanides are versatile modulators of optoelectronic properties owing to their narrow optical emission spectra across the visible and near-infrared range. Their use in metal halide perovskites (MHPs) has recently gained prominence, although their fate in ...

A five-stranded heterometallic helicate

Kay Severin, Farzaneh Fadaei Tirani, Sylvain Alexandre Marie Sudan

A penta-stranded helicate was obtained by combining Pd(CH3CN)42 with La(NO3)3 and a polydentate ligand. The helicate displays low symmetry, both in solution and in the solid state. A dynamic interconversion between the penta-stranded helicate and a ...

Structure and small molecule activation reactivity of a metallasilsesquioxane of divalent ytterbium

Rosario Scopelliti, Marinella Mazzanti

The first metallasilsesquioxane of a divalent lanthanide, Yb{Cy7Si7O11(OSiMe3)}(THF),1, was synthesized and structurally characterized. The Cy7Si7O11(OSiMe3)(2-)ligands in1bind two Yb(ii) ions in a bridging mode. The dinuclear complex effects the two- ...

Colorimetry of Luminescent Lanthanide Complexes

Anne-Sophie Chauvin, Julien Alexandre Andres

Europium, terbium, dysprosium, and samarium are the main trivalent lanthanide ions emitting in the visible spectrum. In this work, the potential of these ions for colorimetric applications and colour reproduction was studied. The conversion of spectral dat ...

Carbon dioxide reduction by dinuclear Yb(ii) and Sm(ii) complexes supported by siloxide ligands

Marinella Mazzanti, Farzaneh Fadaei Tirani, Davide Toniolo

Two dinuclear homoleptic complexes of lanthanides(II) supported by the polydentate tris(tertbutoxy) siloxide ligand ([Yb2L4], 1-Yb and [Sm2L4], 1-Sm, (L = (OtBu)3SiO−)) were synthesized in 70–80% yield and 1-Sm was crystallographically characterized. 1-Yb ...

Molecular Complex of Tb in the +4 Oxidation State

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic

Lanthanides (Ln) usually occur in the +3, or more recently the +2, oxidation states. The only example of an isolated molecular Ln(4+) so far remains Ce4+. Here we show that the +4 oxidation state is also accessible in a molecular compound of terbium as dem ...

Influence of Functionalized η6 -Arene Rings on Ruthenium(II) Curcuminoids Complexes

Paul Joseph Dyson, Rosario Scopelliti, Laure Debora Pittet, Tina Riedel, Agnese Petrini

A series of organometallic Ru(II) complexes containing functionalized η6‐arene ligands, together with curcumin and bisdemethoxycurcumin as O,O’‐chelating ligands and their RAPTA (ruthenium arene complexes bearing the 1,3,5‐triaza‐7‐phosphaadamantane ligand ...

Reduction of a Cerium(III) Siloxide Complex To Afford a Quadruple-Decker Arene-Bridged Cerium(II) Sandwich

Rosario Scopelliti, Marinella Mazzanti, Rory Patrick Kelly

Organometallic multi-decker sandwich complexes containing f-elements remain rare, despite their attractive magnetic and electronic properties. The reduction of the Ce-III siloxide complex, [KCeL4] (1; L = OSi(OtBu)(3)), with excess potassium in a THF/tolue ...

Rising Stars in Science and Technology: Luminescent Lanthanide Materials

Jean-Claude Bünzli

This essay draws attention to lanthanide luminescence by putting into perspective the sensitization process of f-f emission, the design of highly luminescent lanthanide-based compounds, and upconversion nanoparticles. A brief overview of the recent advance ...
