  seven emissive europium(III) and terbium(III) complexes was prepared, incorporating a 3‐pyridyl‐4‐azaxanthone or 3‐pyrazolyl‐4‐azaxanthone sensitising moiety within a polydentate macrocyclic ligand. High overall emission quantum yields in aqueous media are attenuated in the presence of protein or certain oxy anions due to displacement of the N,N′‐chelated sensitiser. Nevertheless, these complexes are
