The synthesis, optical properties, and solid-state structures of a series of o-(aryleneethynylene) oligomers containing three to seven aryl units is described. The main chain in all examples is composed of between one and five 4,5-dimethoxybenzene rings which are capped on each end by 2-pyridyl rings. These oligomers demonstrate pH-dependent emission and absorption spectra. Single crystals were obtained from the aryleneethynylenes containing three to five arene rings. These single crystals were investigated by X-ray diffraction.
描述了一系列含有三至七个芳基单元的邻（亚芳基乙炔）低聚物的合成、光学性质和固态结构。所有示例中的主链由一至五个4,5-二甲氧基苯环组成，两端由2-吡啶环封端。这些低聚物表现出pH依赖性发射光谱和吸收光谱。从含有三至五个芳烃环的亚芳基乙炔中获得了单晶。通过X射线衍射对这些单晶进行了研究。
