Abstract: | On the basis of rhodamine, a versatile trifunctional chemosensor RP has been synthesized. It can selectively and sensitively recognize Cu(2+) and Zn(2+) in different solutions. Based on the zinc-containing [RP@Zn(2+)] complex, it shows highly selective recognition for His/Cys. Fluorescent imaging of Zn(2+) in living cells was also obtained. |
