  摘要：

  使用聚苯胺（PANI）固定的钯作为非均相催化剂，已经获得了一种方便有效的基于苯并硫属元素二唑的小分子合成方法。已经比较了具有不同末端取代基的合成的苯并硫属元素二唑基小分子的光物理性质。此外，已经使用单晶X射线衍射（SCXRD）技术研究了包括共轭分子的堆积模式和非键相互作用在内的结构方面。

  The palladium‐catalyzed direct arylation of benzofurazans with aryl bromides to access 4‐arylbenzofurazans proceeds in moderate‐to‐high yields using phosphine‐free palladium acetate as the catalyst and potassium acetate as an inexpensive base. A wide variety of (hetero)aryl bromides, including bromopyridine and bromothiophene derivatives has been successfully employed. Palladium‐catalyzed one‐pot C‐4

  使用无膦的乙酸钯作为催化剂，乙酸钾作为廉价的碱，钯催化的苯并呋喃酮与芳基溴的直接芳基化反应可制得4-芳基苯并呋喃。已经成功地使用了各种各样的（杂）芳基溴化物，包括溴吡啶和溴噻吩衍生物。使用大量的芳基溴化物也可以实现钯催化的一锅C-4，C-7二芳基苯并呋喃的芳基化反应。此外，也报道了将4-芳基苯并呋喃类衍生物衍生为4-芳基喹喔啉。

  Intramolecular catalyst transfer takes place on dibromobenzotriazole, but not on dibromobenzothiadiazole in the Suzuki–Miyaura coupling reaction and polycondensation reaction with tBu3PPd precatalyst. Furthermore, the addition of benzothiadiazole interfered with catalyst transfer in the coupling reaction of dibromophenylene with phenylboronic acid ester, in which the catalyst transfer occurs in the

  在 Suzuki-Miyaura 偶联反应和t Bu 3 PPd 预催化剂的缩聚反应中，分子内催化剂转移发生在二溴苯并三唑上，但不是发生在二溴苯并噻二唑上。此外，苯并噻二唑的添加干扰了二溴亚苯基与苯基硼酸酯的偶联反应中的催化剂转移，其中催化剂转移在不存在任何添加剂的情况下发生。

  Exemplary thin-film optical devices have first and second layer groups disposed as a layer stack on a substrate. The first layer group comprises a first PPN layer, a first LCP layer, and a first barrier layer all superposed. The second layer group is superposed relative to the first layer group, and includes a second PPN layer, a second LCP layer, and a second barrier layer all superposed. The first and second layer groups cooperate to polarize multiple wavelengths of an incident light flux in a broadband and/or wide-angle manner. Each of the layer groups has an alignment layer, a respective liquid-crystal polymer layer, and a barrier layer.

  Linear photo-oriented polymer (LPP) layers are situated to align liquid crystals in a liquid crystal polymer (LCP) layer situated at or on the LPP layers. The LCP layer can include a guest such as a fluorophore that aligns with the liquid crystal so as to emit polarized fluorescence in response to an excitation beam. Layer LPP/LCP structures can be provided as light emitters, patterned polarizers, patterned retarders and other devices based on selection of one or more guest materials included in the LCP and alignable with the liquid crystal.
