Aryl-Phosphonate Lanthanide Complexes and Their Fluorinated Derivatives: Investigation of Their Unusual Relaxometric Behavior and Potential Application as Dual Frequency 1H/19FMRI Probes

Aryl-Phosphonate Lanthanide Complexes and Their Fluorinated Derivatives: Investigation of Their Unusual Relaxometric Behavior and Potential Application as Dual Frequency 1H/19FMRI Probes

A series of low molecular weight lanthanide complexes were developed that have high 1H longitudinal relaxivities (r1) and the potential to be used as dual frequency 1H and 19FMR probes. Their behavior was investigated in more detail through relaxometry, pH-potentiometry, luminescence, and multinucle...

Zusammenfassung:A series of low molecular weight lanthanide complexes were developed that have high 1H longitudinal relaxivities (r1) and the potential to be used as dual frequency 1H and 19FMR probes. Their behavior was investigated in more detail through relaxometry, pH-potentiometry, luminescence, and multinuclear NMR spectroscopy. Fitting of the 1HNMRD and 17ONMR profiles demonstrated a very short water residence lifetime (
