Rhodamine-based bis-sulfonamide as a sensing probe for Cu2+ and Hg2+ ions
摘要:
一种新型罗丹明基双磺酰胺1的设计与合成已经完成。该受体在CH3CN-水(4/1,v/v;10 μM tris HCl缓冲液,pH 6.8)中通过显示不同的发射特性和颜色变化,选择性地识别Cu2+和Hg2+离子。其中,Cu2+通过发射增强被感知,而Hg2+则通过1的发射中的微弱比率变化被检测到。该受体在体外能够检测人体宫颈癌(HeLa)细胞中的这两种离子。

Rhodamine-based bis-sulfonamide as a sensing probe for Cu2+ and Hg2+ ions
A new rhodamine-based bis-sulfonamide 1 has been designed and synthesized. The receptor selectively recognizes Cu2+ and Hg2+ ions in CH3CN–water (4/1, v/v; 10 μM tris HCl buffer, pH 6.8) by showing different emission characteristics and color changes. While Cu2+ is sensed through increase in emission, Hg2+ is detected by a weak ratiometric change in emission of 1. The receptor shows in vitro detection of both the ions in human cervical cancer (HeLa) cells.
