摘要：
A novel Hg2+-selective fluorescent sensor (Sensor-Hg) based on a rhodamine scaffold, with N-Ethylthioethyl-N-[N',N'-(2'-Diethylthioethylamino)-5'-methyl-Phenoxyethyl]-2-Methoxy Aniline (EDPMA) as a receptor, has been developed. Sensor-Hg exhibited similar to 35-fold enhancement in fluorescence emission upon binding with Hg2+, with a characteristic emission band of rhodamine at similar to 585 nm. It demonstrates high selectivity and sensitivity for detecting Hg2+ in aqueous solution and living cells.
