  A magnetic palladium nickel carbon (Fe3O4@Pd@Ni/C) nanocomposite has been synthesized using a simple one-pot procedure via a hydrothermal approach. Ferric nitrate, palladium acetate, and nickel nitrate were dissolved in water together with glucose, and the mixture was heated in an autoclave. The Fe3O4@Pd@Ni/C nanocomposite was characterized via XRD, TEM, FE-SEM, VSM, EDS, and XPS studies. The catalytic

  It is commonly known that halogenation tends to decrease the luminescence quantum yield of an organic dye, owing to the high electronegativity and heavy‐atom effect of the halogen atom. However, based on an investigation of the effects of halogenation on the luminescence of the oligo(phenylene vinylene) (OPV) framework, we demonstrate that halogenation can have positive impact on the solid‐state fluorescence

  众所周知，由于卤素原子的高电负性和重原子效应，卤化往往会降低有机染料的发光量子产率。但是，基于对卤化作用对低聚（亚苯基亚乙烯基）（OPV）骨架发光的影响的研究，我们证明卤化可以对OPV衍生物的固态荧光和电化学发光（ECL）性能产生积极影响。氯化OPV具有很高的固态荧光量子产率（91％），而溴化类似物具有最高的ECL发射强度。随时间变化的密度泛函理论计算，自然键轨道分析，

  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
