A set of cyclo‐7,10‐tris‐triphenylenyl macrocycles have been prepared by a Yamamoto cyclotrimerization protocol. In these novel macrocycles, three triphenylene units are covalently linked to each other, resulting in the formation of triangular‐shaped molecules. The fully planar derivative revealed pronounced self‐assembly behavior. NMR spectroscopy was used to determine the association constant in
根据Yamamoto的环三聚规程已经制备了一组7-7,10-tris-三亚苯基环。在这些新颖的大环中,三个三亚苯基单元彼此共价连接,从而形成三角形分子。完全平面的导数显示出明显的自组装行为。NMR光谱法用于确定溶液中的缔合常数。二维广角X射线散射被用于研究这种新的盘状液晶元在整体状态下的液晶性。此外,由于非平面,侧向取代的衍生物具有独特的光电特性和高稳定性,因此已成功地作为有机发光二极管中的蓝色发射体进行了测试。在这种情况下,
