  Tunable blue-emitting fluorophores—benzo[1,2-b:4,3-b′]dithiophene and trithia[5]helicene end-capped with electron-rich or electron-deficient aryl substituents

  摘要：

  Light-emitting fluorophores 1-10b based on aryl substituted benzo[1,2-b:4,3-b']dithiophenes (BDT) and trithia[5]helicenes (T5H) have been synthesized using various combinations of Suzuki coupling, the Wittig, or McMurry reaction, and subsequent photocyclization of the dithienylethenes thus obtained. Photophysical properties of the helical compounds end-capped with different electron-rich and electron-deficient aryl moieties thus resulting were evaluated. Photocyclization of a dithienylethene derivative 10a was investigated, and the X-ray crystal structure of dinaphthyl-substituted BDT (4) was obtained. With this series of compounds 1-10b, we demonstrate that the optical properties of all of the new compounds, and by extension many conjugated materials, can be tuned over the entire blue range (400-480 nm).

  A Na2PdCl4-catalysed B2(OH)4-mediated direct cross-coupling of two distinct aryl bromides in pure water is described. This one-step borylation/Suzuki method exhibits an outstanding cross-coupling selectivity and no tendency to produce homocoupling products, therefore leading to biaryls and heterobiaryls in moderate to good yields. Moreover, the reaction has high regio-selectivity and can be scaled-up

  描述了Na 2 PdCl 4催化的B 2（OH）4介导的两种不同的芳基溴化物在纯水中的直接交叉偶联。这种一步式硼化/铃木法显示出优异的交叉偶联选择性，并且没有产生均偶联产物的趋势，因此导致联芳基和杂联芳基的产率中等至良好。而且，该反应具有高的区域选择性并且可以扩大规模。使用这种简单，经济和实用的方案，可以实现3,5-二溴吡啶的不对称二芳基化。

  A series of nonlinear optical chromophores 6 containing a substituted benzothiazole ring have been synthesized and characterized. 1,3-Benzothiazoles 6 were prepared by treating various formyl derivatives of thienyl compounds withortho-aminobenzenethiol in fair to excellent yields. These in turn were prepared by Suzuki coupling between aryl and thienyl precursors. The electronic interactions between
