Trifluoroborate-appended cyclen complexes of paramagnetic transition metals (Ni2+, Co2+) as fast-relaxing 19F MRI probes
{{output}}
For the first time, trifluoroborate groups (BF3) have been investigated as sensitive probes for 19F Magnetic Resonance Imaging (MRI) in paramagnetic complexes. Using a macrocyclic BF3-appended cyclen ligand, complexes of Ni2+ and Co2+ cations were synthesized ... ...
