Abstract

ABSTRACT A new type of styryl bridging triphenyl amine-indolium conjugated dye has been developed for the colorimetric and ratiometric detection of cyanide. The detection of cyanide is confirmed by means of the fast nucleophilic attack of cyanide by the indolium group of the probe that results a speedy sensing process for cyanide with clear color and fluorescence change of the ICT process. The ratiometric fluorescence changes illustrated a linear response in the range of 0-18 μM with a low LOD value (1.7×10-7 M-1). The as-reported sensor not only function as a colorimetric sensor for “in-the-field” measurement by virtue of a “dip-stick” approach but also interact with a human breast cancer cell (MDA-MB 231) which reveals the realistic value of this probe for tracking cyanide anions in biological systems.

用于检测人类乳腺癌细胞和试纸中具有大发射位移的氰化物的比率苯乙烯桥接三苯胺-吲哚基荧光染料

摘要:研制了一种新型苯乙烯桥接三苯胺-吲哚偶联染料，用于氰化物的比色和比色检测。通过探针的吲哚基团对氰化物的快速亲核攻击，证实了氰化物的检测，从而导致氰化物的快速检测过程，具有清晰的颜色和ICT过程的荧光变化。比值荧光变化在0 ~ 18 μM范围内呈线性响应，LOD值较低(1.7×10-7 M-1)。据报道，该传感器不仅可以作为“现场”测量的比色传感器，而且还可以与人乳腺癌细胞(MDA-MB 231)相互作用，这揭示了该探针在生物系统中追踪氰化物阴离子的现实价值。图形抽象

期刊介绍： Supramolecular Chemistry welcomes manuscripts from the fields and sub-disciplines related to supramolecular chemistry and non-covalent interactions. From host-guest chemistry, self-assembly and systems chemistry, through materials chemistry and biochemical systems, we interpret supramolecular chemistry in the broadest possible sense. Interdisciplinary manuscripts are particularly encouraged. Manuscript types include: high priority communications; full papers; reviews, and; Methods papers, techniques tutorials highlighting procedures and technologies that are important to the field. We aim to publish papers in a timely fashion and as soon as a paper has been accepted and typeset it will be published in electronic form on the Latest articles section of the website. The two most important review criteria are that the paper presents high-quality work that fits generally into the broad spectrum of activities in the supramolecular chemistry field. Under normal circumstances, Supramolecular Chemistry does not consider manuscripts that would be more suitable in a highly specialized journal. This includes, but is not limited to, those based mostly or exclusively on topics such as solid state/X-ray structures, computational chemistry, or electrochemistry. . The two most important review criteria are that the paper presents high-quality work that fits generally into the broad spectrum of activities in the supramolecular chemistry field.
