Supramolecular Terbium-Threonine Chiral Emitters with Tunable Circularly Polarized Luminescence as Anticounterfeiting-Ink for Autonomous Data Encryption. [PDF]

Adv Sci (Weinh)
A one‐pot, aqueous, and scalable method for synthesizing chiral lanthanide supramolecular emitters using terbium and threonine is reported. The aqueous solution of these chiral emitters displays the following features: (i) 100 % transparency, (ii) tunable luminescence and CPL, and (iii) a pH feedback loop that controls the “on‐off” states of ...

Phosphine Coordination to Ce, Nd, Np, and Pu in ^ArBiAMP^tBu-Supported Complexes and Their ²H and ¹³C Isotopologues. [PDF]

Adv Sci (Weinh)
A dianionic ligand designed to encourage metal‐phosphine coordination—bis((3,5‐dimethylphenyl)amidomethyl)tertbutylphosphine (ArBiAMPtBu)—was employed in the synthesis of paramagnetic complexes of Ce, Nd, Np, and Pu, producing MI(ArBiAMPtBu)(thf)3.

Novel Antennae for Luminescent Lanthanide Cations Emitting in the Visible and in the Near-Infrared: From Small Molecules to Polymetallic Lanthanide Containing Nanocrystals

CHIMIA, 2009
Lanthanide cations have advantageous luminescence properties in the visible and in the near-infrared, such as high resistance to photobleaching which is a desirable property allowing long exposure of lanthanide compounds to excitation light ...

Encapsulation-Stabilized, Europium Containing Nanoparticle as a Probe for Time-Resolved luminescence Detection of Cardiac Troponin I

Biosensors, 2017
The use of a robust optical signaling probe with a high signal-to-noise ratio is important in the development of immunoassays. Lanthanide chelates are a promising material for this purpose, which provide time-resolved luminescence (TRL) due to their ...

Phosphoserine for the generation of lanthanide-binding sites on proteins for paramagnetic nuclear magnetic resonance spectroscopy [PDF]

Magnetic Resonance, 2021
Pseudocontact shifts (PCSs) generated by paramagnetic lanthanide ions provide valuable long-range structural information in nuclear magnetic resonance (NMR) spectroscopic analyses of biological macromolecules such as proteins, but labelling proteins site-

A Periplasmic Lanthanide Mediator, Lanmodulin, in Methylobacterium aquaticum Strain 22A

Frontiers in Microbiology, 2022
Methylobacterium and Methylorubrum species oxidize methanol via pyrroloquinoline quinone-methanol dehydrogenases (MDHs). MDHs can be classified into two major groups, Ca2+-dependent MDH (MxaF) and lanthanide (Ln3+)-dependent MDH (XoxF), whose expression ...
