The invention provides a method of determining the amount of an analyte having an oxidation potential, for a one electron oxidation process, of about +0.10 to about +1.20 volts at pH 7, relative to the normal hydrogen electrode at 298K, said method comprising measuring the emission intensity or emission lifetime, at two or more wavelengths, from a sample comprising said analyte and two or more different macrocyclic lanthanide (III) complexes, wherein each of said macrocyclic lanthanide (III) complexes comprises a different lanthanide ion but the same macrocyclic ligand, and using a ratio of emission intensities or emission lifetimes measured at two different wavelengths to calculate the amount of analyte in said sample.

The chemical shift of paramagnetically shifted resonances in lanthanide(III) complexes encodes information about temperature and has also been made to report pH in parallel, through introduction of a single phosphonate group adjacent to the reporter tert‐butyl resonance. The enhanced sensitivity of this new probe has allowed the simultaneous triple imaging of the water signal and the shifted tert‐butyl
