A serles of water-soluble fluorescent dendritic compounds composed of phenylene-ethynylene repeating units and anionic carboxylate or catlonlc ammonium peripheral groups were synthesized. The first generation fluorescent dendrlmer containing nine phenylene-ethynylene units and six carboxylate peripheral groups exhibited a highly selective fluorescence quenching by Hg 2+ Ions. The Stern-Volmer constant (K8v) was 33,700 M -1 In aqueous media In the presence of Triton X-100 surfactant.
