changes in calcium ion concentrations in the millimolar regime, signal the presence of citrate selectively in competitive aqueous media and allow the monitoring of remote ester/amide hydrolysis in relayed, irreversible transformations. Chemical shift non‐equivalence is amplified by the presence of the proximate lanthanide ion, with a mean separation between the CF3 group and the metal ion of 6.4 Å found
