  operationally simple homocoupling reaction that targets the convenient synthesis of organic-electronically important building blocks. A variety of synthetically useful bithiophene derivatives and functionalized biphenyls are efficiently prepared by an on-water and under-air protocol using Pd/C as catalyst. We find that Pd/C gives generally higher and cleaner homocoupling conversions than using Pd(OAc)2 in the

  我们在此报告了一种操作简单的均偶联反应，其目标是方便合成有机电子重要的结构单元。各种合成上有用的联噻吩衍生物和官能化联苯可通过水上和空气中协议使用Pd / C作为催化剂有效地制备。我们发现，在（杂）芳基碘化物的情况下，由于Pd（OAc）2的存在，与使用Pd（OAc）2相比，Pd / C的同质耦合转化率更高且更清洁。引发更多的副反应，包括脱卤和低聚。在最佳条件下，对酯，酮，醛，腈，硝基，氯和溴等官能团的耐受性良好。我们希望本方法学将为绿色化学与基于噻吩的有机材料的桥接做出宝贵的合成贡献。
• Optical Activity of Heteroaromatic Conjugated Polymer Films Prepared by Asymmetric Electrochemical Polymerization in Cholesteric Liquid Crystals: Structural Function for Chiral Induction

  日期：2013.3.26

  We electrochemically polymerized various achiral heteroaromatic monomers in left-handed helical cholesteric liquid crystal (CLC) media. Circular dichroism (CD) spectroscopy revealed that most of the resulting conjugated polymer films exhibited both the first negative and second positive Cotton effects near their absorption maxima. This indicates left-handed helical aggregation of the conjugated main

  我们在左旋螺旋胆甾型液晶（CLC）介质中电化学聚合了各种非手性杂芳族单体。圆二色性（CD）光谱显示，大多数所得共轭聚合物薄膜在其吸收最大值附近均表现出第一负棉花效应和第二正棉花效应。这表明共轭主链的左旋螺旋聚集，这与CLC的左旋螺旋顺序一致。该结果表明，在电沉积期间，左旋螺旋CLC环境引起聚合物的左旋螺旋聚集。然而，聚合物的CD强度取决于母体单体的结构。
