A simple way to detect and remove trace amounts of WO4(2-) ions from an aqueous solution was demonstrated by their light-harvesting ability and selective excitation energy transfer to a Tb-doped layered yttrium hydroxynitrate matrix.

Chiral alkyl or amido yttrium complexes were prepared from N-silyl- or N-cyclopentyl-substituted binaphthylamido ligands. According to the synthetic procedure, these complexes could be obtained in their neutral form or as heterobimetallic complexes in the presence of 1 equiv. LiCl. These new species were characterized by IR and NMR spectroscopies, elemental analyses and some of them by X-ray di...

UNLABELLED 111In-Diethylenetriaminepentaacetic acid-octreotide generally is used for the scintigraphic imaging of neuroendocrine and other somatostatin receptor-positive tumors. On the basis of the successful targeting of octreotide, radiolabeled somatostatin analogs, such as 90Y-(1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid [DOTA])0-Tyr3-octreotide and 177Lu-DOTA0-Tyr3-octreot...

Targeted α therapy (TAT) is a promising tool in the of cancer. The radionuclide 213BiIII shows favourable physical properties for this application, but fast and stable chelation metal ion remains challenging. Herein, we demonstrate that mesocyclic chelator AAZTA quickly coordinates BiIII at room temperature, leading to robust complex. A comprehensive study structural, thermodynamic kinetic [Bi(...

This research aimed to develop new tumor targeted theranostic agents taking advantage of the similarities in coordination chemistry between technetium and rhenium. A γ-emitting radioactive isotope of technetium is commonly used in diagnostic imaging, and there are two β- emitting radioactive isotopes of rhenium that have the potential to be of use in radiotherapy. Variants of the 6-hydrazinonic...

A new family of Y(4)/M(2) and Y(5)/M heterobimetallic rare-earth-metal/d-block-transition-metal-polyhydride complexes has been synthesized. The reactions of the tetranuclear yttrium-octahydride complex [{Cp''Y(μ-H)(2)}(4)(thf)(4)] (Cp'' = C(5)Me(4)H, 1-C(5)Me(4)H) with one equivalent of Group-6-metal-pentahydride complexes [Cp*M(PMe(3))H(5)] (M = Mo, W; Cp* = C(5)Me(5)) afforded pentanuclear he...
