  用于单一材料有机太阳能电池的C 60-小芳基胺推拉二元组

  摘要：

  描述了两个二元体的合成，这些二元体通过酯化反应形成的柔性绝缘连接基团连接，包括小的基于芳基胺的推挽系统作为供体嵌段和C 60富勒烯作为受体。在通过循环伏安法和UV-Vis吸收光谱法分析了它们的电子特性后，已经在简单的直接结构装置中评估了这些分子作为单材料有机太阳能电池活性材料的潜力。基本上由于填充因子差，这两种方法均导致约0.40％的适中转换效率。就供体和受体嵌段的纳米相分离不足以及与连接C 60连续的供体嵌段的空穴迁移率下降而言，讨论了这些结果。

• Rigidified merocyanine dyes with different aspect ratios: Dichroism and photostability
  作者：Katharina Christina Kreß、Korinna Bader、Joachim Stumpe、S. Holger Eichhorn、Sabine Laschat、Thomas Fischer

  DOI：10.1016/j.dyepig.2015.04.041

  日期：2015.10

  A series of new rigidified merocyanines were investigated with regard to their optical properties as dichroic dyes. Guest/host-mixtures of the dyes were prepared using a liquid crystal and a reactive mesogen mixture. Their dichroism was studied using linearly-polarized UV/Vis-spectroscopy. A strong dependence of the dichroic ratio on the aspect ratio, the number of double bonds in the molecular structure, and on the maximum wavelength of absorption was found. A strategy to increase the aspect ratio has also been demonstrated. Additionally, the photostability was characterized using continued irradiation with polychromatic light from a xenon source. High photostability was found in all host mixtures in the absence of oxygen by alignment in a matrix. The suitability for their application as dichroic dyes in thin layer polarizers and guest/host-displays is herein discussed. (C) 2015 Elsevier Ltd. All rights reserved.
