A poly(amine ester) dendrimer with naphthyl units (G1N6) has been synthesized as a fluorescent chemosensor for metal ions. We investigated the metal-ion recognition of G1N6 by adding each of Ag+, Al3+, Ba2+, Ca2+, Cd2+, Co2+, Cu2+, Fe3+, Mg2+, Ni2+, and Zn2+ in acetonitrile solution. Large changes were observed in the fluorescence spectra of G1N6 upon the addition of Al3+, Cu2+, and Zn2+.
