Abstract

Dendrimeric rhodamine-derived chemosensor (POSS-Rh8) for highly selective determination of Au in aqueous acidic solutions has been developed. The response mechanism is based on the catalytic destruction of the dendrimeric molecule what provide fluorescence enhancement via reducing intramolecular quenching. The probe exhibits linear signal response and allows determination of Au content in aqueous solutions from 2·10^-7 M.
