Abstract

A phosphorescence chemosensor bearing an iridium (III) complex as a communicating source and two Zn-DPA units acting as a preorganized binding site for H₂PO₄^- is presented. The phosphorescent chemosensor displayed a selective phosphorescence enhancement with H ₂PO₄^- in aqueous solution and at neutral pH. On the other hand, F^-, Cl^-, Br^-, I^-, NO₃^-, CH₃COO^-, and ClO ₄^- did not induce significant changes in phosphorescence. Furthermore, the phosphorescent chemosensor shows selectivity for H ₂PO₄^- over the related phosphate species, such as ATP and pyrophosphate. In addition, there was a distinct lifetime change only for H₂PO₄^-. The association constant was calculated to be 9.68 × 10⁴ M^-1 for H ₂PO₄^-.
