摘要

在本文中，我们合成了一种新型 9,9'-联芴基扩展四硫富戊烯（TTF）的 E/Z 异构体混合物，发现该混合物很容易发生氧化二聚反应，生成一种 TTF 乙烯基对映体，其中两个二硫富戊烯单元连接到一个与联芴基核心融合的八元环上。这种化合物具有多重氧化还原行为，在循环伏安法条件下可产生六种电荷状态：-这种二阳离子对应于带有两个附加 1,3 二硫环的环辛基[1,2,3-jk:6,5,4-j'k']二芴。

Synthesis of Bifluorenylidene- and Cycloocta[1,2,3-jk:6,5,4-j'k']difluorene-Extended Tetrathiafulvalenes – Novel Multi-Redox Systems

Herein, we present the synthesis of a novel 9,9’-bifluorenylidene-extended tetrathiafulvalene (TTF) as an E/Z isomeric mixture that was found to readily undergo an oxidative dimerization to furnish a TTF vinylogue with the two dithiafulvene units connected to an eight-membered ring fused to a bifluorenylidene core. This compound exhibited multi-redox behavior and was found to take six charge states under cyclic voltammetry conditions: -2, -1, 0, +1, +2, +3. The dication corresponds to a cycloocta[1,2,3-jk:6,5,4-j’k’]difluorene with two appended 1,3-dithiolium rings.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
