A novel π-stacked polymer based on a pseudo⁻⁻linked [2.2]paracyclophane moieties was synthesized by Sonogashira-Hagihara coupling. The UV-vis absorption spectra of the synthesized polymer and model compounds revealed an extension of the conjugation length owing to the through-space conjugation. The optical properties of the π-stacked dimer with the pseudo⁻⁻linked [2.2]paracyclophane unit were compared with those of the corresponding dimers with the pseudo⁻⁻ and pseudo⁻⁻linked [2.2]paracyclophane units.
通过Sonogashira-Hagihara偶联反应合成了一种基于伪连接的[2.2]对环芳烷部分的新型π-堆积聚合物。合成聚合物和模型化合物的紫外-可见吸收光谱表明，由于空间共轭，共轭长度得到了延长。将具有伪连接[2.2]对环芳烷单元的π-堆积二聚体的光学性质与具有伪连接和伪连接[2.2]对环芳烷单元的相应二聚体的光学性质进行了比较。
