Pyrene labelled Zn2+-cyclen 1 and bis-Zn2+-bis-cyclen 2 complexes were synthesized. The reversible coordination at physiological pH of Zn2+-cyclens to phosphate anions and to imide moieties, as present in thymine and uracilnucleotides, is well known. In the presence of analytes bearing a phosphate and an imide or two phosphate groups the formation of a ternary complex consisting of two pyrene-labelled
