Benefiting from the unique properties of Lanthanide ions

Article Abstract:

The synthetic methods allowing the introduction of the spherical ions with fascinating optical and magnetic properties into elaborate mono and polymetallic edifices are reviewed. These methods are illustrated by selected examples describing the use of a coronand to produce luminescent liquid crystals, derivatized calixarenes for 4f-5f element separation, podates for the production of nanoparticles with high relaxivity and for sensitizing the near infrared emission.

Combined spectroscopic/computational studies on Fe- and Mn-dependent superoxide dismutases: insights into second-sphere tuning of active site properties

Article Abstract:

Superoxide dismutases (SODs) are metalloenzymes that protect aerobic organisms from oxidative damage mediated by the superoxide radical. The second-sphere residues involved in controlling both thermodynamic and kinetic properties of the Fe- and MnSOD active sites are demonstrated by combined spectroscopic/computational methodology.
