AbstractGold ions have high activity and cytotoxicity completely different from elemental gold. It is necessary and critical to develop Au3+ detection tools that are easy to operate, intuitive, inexpensive, and non-destructive testing. Here, we propose a novel two-photon fluorescent probe named DA for detecting Au3+, which is a rare combination of dicoumarin with dimethylthiocarbamate for the first time. Based on the PET mechanism, DA turns-on the fluorescence to yellow-green after specifically binds to Au3+, and the reaction is completed within 5 min. The detection limit is as low as 27.60 nM. Simultaneously, DA achieved qualitative and quantitative detection of Au3+ in environmental water samples, and fluorescence imaging of Au3+ in biological cells.
