  摘要：

  我们报告了由 4-氯-2(3 H )-苯并噻唑酮 ( CBT )自组装成全色纤维形成的结构的合成和表征及其在细胞成像中的应用。在不同的溶剂和浓度下广泛研究了合成化合物的聚集特性，并通过各种显微技术，如原子力显微镜 (AFM)、荧光显微镜和光学显微镜，在超分子水平上检查了它们的形态。有趣的是，CBT形成的自组装结构揭示全色发射特性，并在不同激发波长下显示蓝色、绿色和红色荧光。通过不同的技术，如浓度依赖性1 H-NMR、ATR-FTIR、紫外-可见光谱和荧光光谱，研究了自组装结构的形成机制。最后，证明了CBT在细胞成像应用中的效用，可以注意到CBT被哺乳动物细胞有效吸收，细胞在蓝色、绿色和红色通道中显示全色发射。观察到的荧光强度为蓝色 > 绿色 > 红色，有趣的是染料没有表现出任何荧光猝灭。

  日期：2018.10.1

  A one‐pot universal approach for transforming arylamines to aryl halides via reaction with sodium nitrite (NaNO2) and N‐halosuccinimide (NXS) in DMF at room temperature under metal‐ and acid‐free condition is described. This new protocol that is complementary to the Sandmeyer reaction, is suggested to involve the in situ generation of nitryl halide induce nitrosylation of aryl amine to form the diazo
