  A new triphenylamine fluorescent dye for sensing of cyanide anion in living cell

  摘要：

  A triphenylamine-based fluorescent probe 1 with larger Stokes shift (similar to 141 nm) has been synthesized, which can make an efficient nucleophilic addition by reacting with CN- in water. Upon addition of CN-, the red fluorescence of 1 was distinctly quenched. Importantly, 1 exhibits a highly selective response toward CN- over other anions in water and a high sensitivity (detection limit <= 11 nM). More-over, it has potential application to track CN- levels in living cells by confocal laser scanning microscopy (CLSM). (C) 2013 Elsevier Ltd. All rights reserved.

  Light-emitting materials have been widely studied for their promising applications in chemical and biological science. Here we report three phenanthrene-21-crown-7 functionalized fluorescent Pt(II) rhomboidal metallacycles which were then converted into fluorescent supramolecular oligomers by reacting with a bis-ammonium linker. One of these constructs shows concentration-dependent fluorescence in a wide color range, where orange emission at high concentration and blue emission at low concentration was observed. Moreover, at a concentration of 29 µM the same ensemble emits white light that has emerged from the integration of the complementary orange and blue color from the metallacycles and linker, respectively. This study shows how light-emitting materials can be obtained by the proper implementation of multiple orthogonal interactions in a single process.

  发光材料因其在化学和生物科学中的应用前景广泛受到研究。在这里，我们报告了三种苯并-21-冠-7功能化的荧光铂(II)菱形金属环，然后通过与双铵连接剂反应将其转化为荧光超分子寡聚物。其中一种构造物在浓度依赖的范围内显示出广泛的颜色范围的荧光，高浓度时观察到橙色发射，低浓度时观察到蓝色发射。此外，在29 µM的浓度下，相同的整体发射出从金属环和连接剂分别集成的互补橙色和蓝色的白光。这项研究展示了如何通过在单个过程中正确实施多个正交相互作用来获得发光材料。
