• Synthesis and optical properties of a novel sugar coated poly(p-phenyleneethynylene) effectively quenched by concanavalin A

  The synthesis of a novel sugar coated poly(p-phenyleneethynylene) (PPE) via Pd-catalyzed Sonogashira reaction and its subsequent interaction with concanavalin A (Con A) are described. UV–Vis and fluorescence spectra were employed to investigate the response of the polymer toward various concentrations of Con A. The polymer showed a green fluorescence which can be quenched by Con A due to complex formation

• The oligomer approach: An effective strategy to assess phenylene vinylene systems as organic heterogeneous photocatalysts in the degradation of aqueous indigo carmine dye

  electron sacrificial donor was demonstrated as an effective approach to enhance the OPVs photocatalytic activity. However, a significant decrease in activity during the first three irradiation cycles was observed, indicating that the enhancement in photo- and chemical stability is required for further dye-contaminated water treatment applications.

  通过Mizoroki-Heck交叉偶联反应合成了四种低聚亚苯基亚乙烯基（OPV），以更深入地了解亚苯基亚乙烯基系统在水性介质中用于靛蓝胭脂红（IC）染料的多相光催化降解时的机理和命运。OPV在500 nm附近显示可见光吸收并具有可观的发射特性。使用自由基清除剂，单线态氧（1 O 2）捕集阱和ESI-IT-MS研究了OPV系统在靛蓝胭脂红水溶液上的稳定性，机理和光降解活性。确认超氧自由基（O 2 ·-），1 O 2和直接氧化是造成染料降解的原因。在中性pH条件下不会发生氢氧根自由基的形成，并且光催化剂的HOMO和LUMO含量证实了这一点。另外，草酸作为电子牺牲供体的使用被证明是增强OPVs光催化活性的有效方法。但是，观察到在前三个辐照循环中活性显着下降，这表明光和化学稳定性的增强是进一步被染料污染的水处理应用所必需的。

  A polyaniline‐anchored palladium catalyst was prepared and screened for coupling reactions of aryl halides. The robust and recyclable catalyst was effective in Mizoroki–Heck and Suzuki–Miyaura reactions of aryl bromides and aryl iodides. The catalyst system was further employed for one‐pot Wittig–Heck and Wittig–Suzuki combinations to build conjugated compounds in good conversions. Copyright © 2014
