Synthesis of lanthanide and lanthanide-silicate aerogels

Journal of Sol-Gel Science and Technology, 1994
In this paper we report on the preparation of mixed lanthanide-silicate and pure lanthanide aerogels from the chlorides of erbium, praseodymium, and neodymium. A two-step sol-gel method is described for preparing the mixed aerogels, using a sub-stoichiometric amount of water in the first step to prepare a partially condensed silica-lanthanide precursor.

Lanthanide corroles: a new class of macrocyclic lanthanide complexes

Chemical Communications, 2013
The first examples of lanthanide corroles are prepared by two synthetic routes. (Mes2(p-OMePh)corrole)La·4.5DME (1·4.5DME) and (Mes2(p-OMePh)corrole)Tb·4DME (2·4DME) are prepared from the free base corrole and Ln((NSiMe3)2)3, while (Mes2(p-OMePh)corrole)Gd·TACNMe3 (3·TACNMe3) is prepared by metathesis of the recently reported Li3 corrole and GdCl3.

Design of Lanthanide Fingers: Compact Lanthanide‐Binding Metalloproteins

ChemBioChem, 2010
AbstractLanthanides have interesting chemical properties; these include luminescent, magnetic, and catalytic functions. Toward the development of proteins incorporating novel functions, we have designed a new lanthanide‐binding motif, lanthanide fingers.

From lanthanide chlorides to lanthanide pentafluorophenolates via lanthanide N,N-dialkylcarbamates

Polyhedron, 2015
Neodymium and terbium pentafluorophenolates, containing 1,10-phenanthroline as ancillary ligand, [Ln(OC6F5)3(phen)3], (1 Ln = Nd, 2 Ln = Tb) have been synthesized by reacting the N,N-dibutylcarbamato complexes, [Ln(O2CNBu2)3], easily obtained from aqueous solutions of lanthanide salts, with C6F5OH in the presence of 1,10-phenanthroline.

Lanthanide Texaphyrins as Photocatalysts

Inorganic Chemistry, 2018
Here, we report the use of gadolinium(III)-, lutetium(III)-, and lanthanum(III)-texaphyrins as bioinspired photocatalysts that promote a novel approach to the degradation of curcumin, a 1,3-diketo-containing natural product. Complexation of curcumin to the lanthanide centers of the texaphyrins yields stable species that display limited reactivity in ...

Multiphoton Excitation of Lanthanides

ChemPhysChem, 2001
Without requiring chelation by sensitizers, a method to detect lanthanides by multiphoton excitation is reported. This suggests the use of lanthanides as calcium analogues in multiphoton microscopy. The spectrum shows the normalized two-photon excitation emission spectra (λex = 796 nm) of Eu(3+) with a resolution of about 8 nm.

Lanthanides

Lanthanides, formerly known as rare earths, are critical materials. Their discovery, extraction and refining are described. The important role China has in refining is outlined, as is its dominant role in production of components such as extremely powerful permanent magnets based on neodymium–iron–boron alloys.

Lanthanides as Anticancer Agents

Current Medicinal Chemistry-Anti-Cancer Agents, 2005
The application of inorganic chemistry to medicine is a rapidly developing field, and novel therapeutic and diagnostic metals and metal complexes are now having an impact on medical practice. Advances in biocoordination chemistry are crucial for improving the design of compounds to reduce toxic side effects and understand their mechanisms of action.
