The synthesis and spectral properties are reported of a set of four europium(III) complexes containing between one and four 3-azaxanthone sensitising chromophores. Each complex is based on a macrocyclic cyclen core. The emission and aqueous solution 1 H NMR spectral properties are compared, revealing information about the local complex symmetry on the experimental timescale. A C 2 -symmetric mono-cationic
