Abstract

Several azaxanthone and azathioxanthone sensitising chromophores have been incorporated into macrocyclic ligands and form well-defined Eu and Tb complexes in polar media. Excitation of the heterocyclic chromophore in the range 330 to 382 nm leads to modest amounts of aromatic fluorescence and relatively efficient metal-based luminescence, with absolute metal-based quantum yields of up to 24% in aqueous media.

The authors regret the following error:
The structure of compound 2 on page 1709 should have an endocyclic S in place of the O that is drawn for 2a and 2b. Also, the vertical
axis in Figure 1 should read relative intensity not absorbance.
