  二氢吲哚并嗪的光致变色。第XXIV部分：在具有多可寻址光致变色性质的芴基二氢吲哚并嗪的合成中开发“点击”化学策略

  摘要：

  利用“点击”化学方法有效地制备了新种类的光致变色二氢吲哚并二苯并（DHI），其在芴骨架（区域A）中结合了取代的2,7-和4-取代的四唑和恶二唑部分。使用某些分析和光谱技术对所有合成前体以及目标光致变色DHI的结构进行了阐明。通过在DHI骨架的不同位置引入取代基，母体二氢吲哚嗪的高度可调节的光致变色行为是可能的。例如，芴部分的2，7和4位的取代基显示出扩展光致变色的能力。研究了在芴部分（A区）取代的光致变色DHI的光致变色行为，如反应动力学和荧光性质及其耐光疲劳性。已经公开了用恶二唑部分取代（区域A）中2，7-位的四唑部分对光谱，动力学特性，荧光发射和光稳定性都具有强的作用。这项工作的观察结果表明，芴部分中的取代基会影响热背反应速率，并在控制开放形式的所有光致变色特性中起着至关重要的作用。芴中的新合成取代基（DHIs）被2,7-位的四唑部分和2，中的恶二唑部分取代 芴部分的7和4位使这些材料

  Synthesis, Structures, and Photoinduced Electron Transfer Reaction in the 9,9‘-Spirobifluorene-Bridged Bipolar Systems

  摘要：

  A series of 9,9'-spirobifluorene-bridged bipolar compounds DnAm bearing various n:m ratios for triarylamine (D) versus 1,3,4-oxadiazole-conjugated oligoaryl moiety (A) have been synthesized to investigate the corresponding photoinduced electron transfer (PET) property. The excitation behaviors were probed by steady-state absorption, emission, fluorescence solvatochromism, and femtosecond fluorescence up-conversion spectroscopy. The overall reaction dynamics can be rationalized by the rate of PET, in combination with solvent relaxation dynamics. It was found that the rate of PET is dependent on the anchored D/A ratio. The rate of D1A1 and D2A1 was resolved to be similar to 2.44 x 10(12) and 2.32 x 10(12) s(-1), respectively, while it is irresolvable in D1A2 and D2A2 (> 6.6 x 1011 s-1). In another approach, based on the comprehensive X-ray data, cyclicvoltammetry, and absorption/emission spectra, the rate of photoinduced electron transfer was also qualitatively estimated. Fair comparisons were made between experimental and theoretical approaches to gain detailed insight into the PET for the titled systems.
