  spectroscopies. The results showed that, with only one exception, the ED and EW groups at the ends of OPV systems lead to a bathochromic shift. This effect is intensified with the introduction of methoxy groups on the central ring. Consistent with these, the HOMO-LUMO gaps (ΔE) decreases as the strength of ED and EW substituents increases. The ED and EW substituents also lead to a decrease in the Φ f values

  摘要 为了研究分子结构对全反式亚苯基亚乙烯基低聚物 (OPV) 光学性质的影响，16 种 1,4-二苯乙烯基苯衍生物（ 1a-i 和 2a-g ）具有不同的给电子（ED）功能。 ) 和吸电子 (EW) 基团通过 Mizoroki-Heck 交叉偶联反应以中等至良好的产率（40-95%）合成。所实施的方法，经过我们小组先前报道的小改动，可以获得所需的乙烯基构型以及一种新型 OPV 化合物 (1h)。在通过几种技术（例如 FTIR、 1 H、 13 C 和固态核磁共振）进行结构表征后，特别强调通过紫外-可见光和荧光光谱研究它们的光学特性。结果表明，除了一个例外，OPV 系统末端的 ED 和 EW 组导致红移。随着在中心环上引入甲氧基，这种效果得到加强。与这些一致，HOMO-LUMO 间隙（ΔE）随着 ED 和 EW 取代基强度的增加而减小。ED 和 EW 取代基也会导致 Φ f 值降低。这种在

  Two series of OPVs (oligo(phenylenevinylene)), that is, ((1E,1'E)-(2,5-dimethoxy-1,4-phenylene)bis (ethene-2,1-diyl))dibenzene derivatives and 4-((E)-4-((E)-styryl)styryl)pyridine derivatives with different functional groups of varying electronic properties have been synthesized by one-pot Wittig-Heck methodology. The synthesized derivatives have been studied for their optical properties. Amongst them the ((1E,1'E)-(2,5-dimethoxy-1,4-phenylene)bis(ethene-2,1-diyl))dibenzene derivatives with appropriate changes in the end group showed a significant impact on the UV absorption and emission spectra. Particularly NO2-OPV showed distinct solvatochromism in the wavelength range of 218 nm in different solvents. Whereas 4-((E)-4((E)-styryl)styryl)pyridine derivatives showed clear acidochromism which can be detected visually as well as spectroscopically. (C) 2015 Elsevier Ltd. All rights reserved.

  2,5-Bisvinyl-1,4-benzoquinones 1 and 2-vinyl-1,4-benzoquinones 2 substituted with aryl or ester end groups have been synthesized. The 2,5-bisstyryl-1,4-benzoquinones 1 (R=phenyl, p-tolyl, o-tolyl) crystallize with a 7 Angstrom-stacking axis. But only for the o-tolyl derivative the contacts between the vinyl groups are close enough to allow a four-center type photopolymerization. The ester derivative 1 (R=COOEt) has a layer structure and can be photooligomerized in the crystal. The generated cyclobutane subgroups have twofold symmetry. The vinylquinones 2 (R=aryl) may be dimerized photochemically in the crystal at the vinyl groups to centrosymmetric cyclobutanes. Crystals with 4 Angstrom stacking axis are also photoreactive.
