Aryl‐Phosphonate Lanthanide Complexes and Their Fluorinated Derivatives: Investigation of Their Unusual Relaxometric Behavior and Potential Application as Dual Frequency 1 H/ 19 F MRI Probes
A series of low molecular weight lanthanide complexes were developed that have high 1 H longitudinal relaxivities ( r 1 ) and the potential to be used as dual frequency 1 H and 19 F MR probes. Their behavior was investigated in more detail through relaxometry, pH‐potentiometry, luminescence, and mul...
