A new type of organic electronic material, consisting of long alpha-oligofurans containing up to nine rings, was synthesized and characterized. alpha-Oligofurans are highly fluorescent, with a quantum yield in the range 58-74%. They are more rigid than the corresponding oligothiophenes, with tighter herringbone packing. The calculated twisting energy of oligofurans is significantly higher than that of other conjugated heterocycles. Despite their greater rigidity, oligofurans are more soluble than oligothiophenes. The introduced long oligofurans fulfill the most important requirements for a wide range of applications as organic electronic materials.
一种新型的有机电子材料,由含有多达九个环的长 α-寡呋喃组成,已被合成并进行了特性描述。α-寡呋喃具有很高的荧光性,量子产率在 58-74%之间。与相应的寡噻吩相比,它们更具刚性,具有更紧密的鲱鱼骨堆积。寡呋喃的计算扭转能明显高于其他共轭杂环。尽管它们的刚性更大,但寡呋喃比寡噻吩更具可溶性。所引入的长寡呋喃满足了作为有机电子材料广泛应用的最重要要求。
