[Yb(AAZTA)(H2O)]: an unconventional ParaCEST MRI probe

Author affiliations

Abstract

An unexpectedly slow exchange rate has been observed for the coordinated water molecule of [Yb(AAZTA)(H2O)] using 1H-NMR and CEST-MRI studies. This made it possible for the first time to exploit the bound water molecule of a LnIII complex with carboxylic donor groups for CEST imaging. This result envisages the development of a new family of thermodynamically stable ParaCEST probes based on anionic chelates.
