The core-level spectra for the lanthanide metal, dysprosium, are presented. exhibit significant multiplet splitting, which must be included accurate quantification of metallic state. Within paper, modified relative sensitivity factors presented some regions, together with recommended backgrounds integration limits and types.
A new tripodal ligand has been designed by coupling pyridyldicarbonyl binding strands with a triazatriangulenium platform (TATA). The complexation reaction with europium provides a C(3)-symmetrical mononuclear compound that is characterized with NMR, ESMS and qualitatively with single-crystal X-ray crystallography. In addition, photophysical studies of this dual emissive system have been perfor...
We report the response of the electrical conductivity of semiconducting single-walled carbon nanotube (SWNT) thin films on exposure to metal vapors of the early lanthanides under high vacuum conditions. We attribute the strongly enhanced conductivities observed on deposition of samarium and europium to charge transfer from the metals to the SWNT backbone, thereby leading to the first examples o...
Two tridentate and one bidentate binding strands have been anchored on a carbon atom to provide a new unsymmetrical tripodal ligand L for Ln(III) coordination. The ligand itself adopts a single conformation in solution stabilized by intramolecular hydrogen bonds evidenced in the solid state. The reaction of L with trivalent lanthanides provides different coordination complexes depending on the ...
