Procedure
An ethanolic solution (1 mM) of the di-sodium salt of the product from Example 21 was prepared by the addition of 2 equivalents of 1 M NaOH in water. A fluorescence spectrum was run on the resultant solution; excitation λex 328 nm and gave emission peaks (λem) at 422 nm. Titration experiments were conducted by adding known quantities (μl of a 0.1 M ZnCl2 solution) of metal salts and the emission spectrum were recorded after each addition. A two and a half fold increase in fluorescent intensity of the solution was observed on addition of one equivalent of zinc nitrate. This di sodium (9-anthracyl)-N-benzylamine-methylphosphonate solution could sense, significant and reproducible increase in fluorescent intensity, Zn+2 concentrations down to 10−8M.
