Abstract
We report a one-pot, two-step strategy to synthesize fluorescent gold nanodots (AuNDs) co-modified with 1-(10-mercaptodecyl)-5-methylpyrimidine-2,4-dione (TSH) and 11-mercaptoundecanoic acid (MUA) through a ligand exchange reaction and demonstrate their capability of selective sulfide sensing in aqueous media on the basis of fluorescence recovery.
摘要
我们报告了一种一锅两步策略，通过配体交换反应合成了同时修饰 1-(10-巯基癸基)-5-甲基嘧啶-2,4-二酮（TSH）和 11-巯基十一酸（MUA）的荧光金纳米点（AuNDs），并基于荧光恢复证明了它们在水相介质中对硫化物的选择性传感能力。
