  hybrid polyphenylenes featuring controlled orientations and dosages of the doping B3N3 rings have been prepared. Detailed photophysical investigations showed that as the doping dosage is increased, the strong luminescent signal is progressively reduced. This suggests that the presence of the B3N3 rings engages additional deactivation pathways, possibly involving excited states with an increasing charge-separated

  首次报道了利用乙炔基和乙炔基之间的脱羰[4 + 2] Diels-Alder环加成反应合成两个系列的硼氮杂掺杂聚苯，其中一个或多个芳基单元被硼嗪环取代。四苯基环戊二烯酮衍生物。由于硼嗪核的 N 和 B 原子上的芳基取代基上的不同基团可以对硼嗪核进行功能化，因此我们制备了具有不同掺杂剂量和取向的硼嗪掺杂聚亚苯基。为此，制备了两个分子模块：核心和支化单元。根据中心芳族模块和反应基团的化学性质，模块的每个共价组合产生一种独特的掺杂模式。通过这种方法，已经制备了具有可控取向和剂量的掺杂 B3N3 环的三和六支化杂化聚苯。详细的光物理研究表明，随着掺杂剂量的增加，强发光信号逐渐减弱。这表明 B3N3 环的存在参与了额外的失活途径，可能涉及具有增加的电荷分离特性的激发态，这在全碳类似物中受到限制。值得注意的是，对于那些具有低掺杂剂量的杂化聚苯结构，观察到取向掺杂对荧光量子产率的强烈影响。最后，我们表明

  diphenylacetylenes can be isolated in 76–98 % yield. The aqueous catalyst solution can be recycled four times with decreasing activity; however, yields between 93 and 98 % can still be achieved with extended reaction times. Several water‐insoluble products can be isolated in excellent yield by simple filtration and purification by washing with water; this method is used, for the first time, for this type

  with copper(I) chloride was employed for the first time in Sonogashira cross-coupling reactions of phenylacetylene with various aryl halides. The goal was to use an efficient green media by using copper instead of palladium in metal-catalyzed coupling reactions. Monobenzyl nicotinium chloride, a quaternary ammonium salt containing a coordinating centre, plays an important role in this catalytic system

  在苯基乙炔与各种芳基卤化物的Sonogashira交叉偶联反应中，首次采用了一种新颖有效的催化体系，该体系采用氯化单苄基烟碱与氯化铜（I）结合。目标是通过在金属催化的偶联反应中使用铜代替钯来使用高效的绿色介质。单苄基氯化烟碱，一种含配位中心的季铵盐，在该催化体系中起重要作用，并提高了Cu（I）反应过程中的种类。在135–140°C下，短时间内在DMF中以中等至极好的收率生产了许多内部炔烃。将该催化体系的效率与由没有N-给体活性位点的二苄基氯化铵制得的铜基催化剂进行了比较，其中由于缺乏配位位点而观察到了较低的活性。
