To investigate the potential of di- and tri-azaheterocycles as building blocks for pi-conjugated materials with high electron affinity, linear oligomers incorporating pyrazine and a C(3)-symmetric discotic molecule based on triazine were synthesized. The tridodecyloxyphenyl end-capped ethynylene pyrazinylene oligomers showed remarkable solvatochroism in absorption and emission in solution. The oligomers
为了研究二氮杂和三氮杂杂环作为具有高电子亲和力的pi共轭材料的基础的潜力,合成了吡嗪和基于三嗪的C(3)对称盘状分子的线性低聚物。十三烷基氧苯基封端的亚乙炔基吡嗪烯低聚物在溶液中的吸收和发射方面显示出显着的溶剂化现象。含有一个和两个吡嗪环的低聚物在固态下显示出液晶性。包含三个吡嗪环的最大乙炔基吡嗪烯低聚物在-1.08 V时具有最低的首次还原电势。三嗪衍生的盘状分子表现出与线性低聚物相当的UV / Vis和荧光性能,并在-1.49 V时具有首次还原电势,比预期的要低。
