Abstract

A ratiometric fluorescent probe for Pd²⁺ has been constructed through appending indole to rhodamine B. The response process of Pd²⁺ to probe was also verified by UV-vis, fluorescence, ESI-MS, ¹H NMR and density functional theory calculation. Moreover, the highly sensitive and selective probe was successfully applied to monitor Pd²⁺ in living cells.
