Cellular Membrane‐Targeted Europium(III) Probe for Selective and Time‐Resolved Detection of Peroxynitrite

Chemistry – A European Journal, EarlyView.
We report a cellular membrane‐targeted europium(III) probe, Eu.Chol, that enables selective, time‐resolved detection of peroxynitrite (ONOO−) at the cell membrane interface. Eu.Chol demonstrates efficient incorporation into liposomes and Jurkat cells, with minimal response to H2O2, establishing a modular platform for subcellular ONOO− sensing ...

Interpreting Europium Anomalies in Zircon: The Importance of Source Redox

Geochemistry, Geophysics, Geosystems
The sources of granitoids are variably oxidized due to the diversity of environments in which they form. This environmental and consequent chemical variability leads to differences in mineral assemblages, proportions, and compositions of ferric and ...

Europium Doped Atomically Precise Bismuth Oxido Nanoclusters as Molecular Building Blocks for Photoluminescent Hybrid Materials

Chemistry – A European Journal, EarlyView.
Europium doping of bismuth oxido nanoclusters (BiO‐NCs) provides stable hosts for Eu3+ in an asymmetric coordination environment, which in turn results in an intense 5D0→7F0 transition and long luminescence lifetimes. Transparent hybrid materials showing characteristic red photoluminescence are accessible via radical copolymerisation of these soluble ...

Formation of Lanthanide Luminescent Aggregates With RNA Using Tripodal Europium [Eu(III)] BTA Self‐Assembled Complexes

Chemistry – A European Journal, EarlyView.
The two Eu(III) complexes of 1.Eu and 2.Eu, that were formed in situ, were used to bind to yeast RNA and A10 (RNA) in a buffered pH 7 solution. The interaction gave rise to changes in the lanthanide‐centered emission because of direct binding of these complexes, which resulted in aggregation of the RNA, as demonstrated using phase‐contrast and atomic ...

Persilylated and Related Silyl Anion‐Induced Synthesis of Group 3–10 Metal–Silyl Complexes

Chemistry – A European Journal, EarlyView.
Persilylated and related silyl anions serve as powerful tools for constructing metal–silyl complexes across group 3–10 elements. Their strong σ‐donating ability and steric bulk stabilize low‐coordinate, reactive species and enable unique bonding motifs.
