摘要

A highly sensitive colorimetric and red-emitting fluorescent dual probe was synthesized and applied to imaging palladium species based on the Tsuji–Trost reaction. Notably, it displayed specific and turn-on fluorescent response toward Pd0 with a vivid color change from yellow to purple in aqueous media. The detection limit was calculated to be as low as 0.78 nM. Furthermore, the probe was successfully applied for fluorescence imaging of palladium in living cells. All these properties made this probe a promising useful tool not only in environmental detection but also more widely in bioanalytical fields.
