【 摘 要 】

Selective mercuration at the 1,6-positions of 2-hydroxy derivative of Nile Red and its application towards Hg2+- selective signaling was investigated. The 2-hydroxy Nile Red exhibited a selective UV-vis absorption and fluorescent signaling behavior towards Hg2+ ions over common coexisting physiologically important metal ions in aqueous environment. 1H NMR studies revealed that the mercuration was selectively effected at the 1,6-positions of 2-hydroxy Nile Red, which is quite different from that at the 6,8-positions for the parent Nile Red.
