FLUORINATED LANTHANIDE PROBES FOR 19F MAGNETIC RESONANCE APPLICATIONS

摘要

The invention provides a paramagnetic lanthanide (III) complex comprising a lanthanide (III) ion and a polydentate ligand wherein the polydentate ligand comprises one or more fluorine atoms in which the distance of at least. one of the fluorine atoms to the lanthanide ion is less than 7Å, said polydentate ligand not being a DPTA bisamide of p-CF₃- aniline.
