中文摘要:
一新基于 thioimide 荧光灯为 Hg 2+ 的高度选择、敏感的察觉的刺激和发色的 chemodosimeter 被开发了。chemodosimeter 从黑暗绿色显示出答案的显著颜色变化到不仅在 Hg 2+ 离子,而且 100 褶层改进的增加之上无色荧光灯在水的 acetonitrile 的紧张。察觉机制源于 Hg 2+ 到它的 imide 先锋的 thioimide 的导致的 desulfurization。当 chemodosimeter 被装配进 nanoparticles 时,它能也展出颜色变化,荧光改进,和 Hg 2+ 的高度选择、敏感的察觉的显著地双的反应。
英文摘要:
A new thioimide-based fluorescent ‘turn-on’ and chromogenic chemodosimeter for highly selective and sensitive detection of Hg^2+ has been developed. The dual response of Hg^2+ was not only in the marked color change of the solution from dark green to colorless, but also in the significant enhancement of the fluorescent intensity of the chemodosimeter in aqueous acetonitrile. Moreover, when the chemodosimeter was assembled into nanoparticles, it could also exhibit remarkably dual response of color change and fluorescence enhancement for detection of Hg^2+.
