A comparative study of two structural isomers highlights the advantages of bifuran vs. bithiophene units in conjugated systems, such as higher fluorescence, solubility, and increased stability of the oxidized species. Importantly, we have found that the small bifuran unit bestows the advantages found in longer oligofurans, and should be considered in the rational design of π-conjugated systems.
两种结构异构体的比较研究突出了双呋喃与双噻吩单元在共轭体系中的优势,如更高的荧光、溶解性以及氧化物种稳定性的提高。重要的是,我们发现小的双呋喃单元赋予了更长的齐聚呋喃所具有的优势,因此在设计π-共轭体系时应予以考虑。
