Emissive terbium complexes, suitable for protein conjugation, incorporating a pyrazoyl-1-aza-xanthone chromophore have been prepared; they exhibit cellular uptake and possess a much lower sensitivity to excited state quenching.

Lanthanide (III) Ion completing compound comprising: (1) a sensitizer moiety of Formula (I) in which: a is an integer from 1 to 4; b is an integer equal to 1 or 2; c is an integer equal to 1 or 2; (R1)a, (R2)b, (R3)C are the same or different and are chosen from the group consisting of H; alkyl; -COOR4 where R4 is H or an alkyl; aryl; heteroaryl; saturated or unsaturated cyclic hydrocarbon; CF3; CN; a halogen atom; L-Rg; L-Sc; or two consecutive R3, two consecutive R2 or two consecutive R1 groups together form an aryl or a heteroaryl group or a saturated or unsaturated cyclic hydrocarbon group; where L is a linker, Rg is a reactive group and Sc is a conjugated substance; X1 and X2 are the same or different and are O or S; A is either a direct bond or a divalent group chosen from -CH2- or -(CH2)2-, said moiety being covalentiy attached to (2) a lanthanide (in) ion chelating moiety through A. The above compounds are used in the preparation of luminescent lanthanide (III) ion complexes which are used as fluorescent labels.

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
