四硫富瓦烯 (TTF) 功能化的最新进展使 TTF 单元能够共价连接到大分子系统中。提出了包含 TTF 单元的树枝状大分子的收敛合成，包括 (TTF)(13) 系统，其中 TTF 单元位于结构层次的所有层。薄层循环伏安法已确定 TTF 的氧化还原活性保留在这些大分子中：所有 TTF 单元依次氧化为自由基阳离子和双阳离子，在溶液中产生高电荷物质。还描述了包含围绕酞菁核心构建的四个和八个 TTF 单元的大分子。这些材料呈现出具有多电子氧化还原活性关键特性的新颖结构。
Recent developments in the functionalisation of tetrathiafulvalene (TTF) have enabled TTF units to be covalently linked into macromolecular systems. Convergent syntheses of dendrimers containing TTF units are presented, including a (TTF)(13) system in which TTF units are emplaced at all layers of the structural hierarchy, Thin layer cyclic voltammetry has established that the redox activity of TTF is retained in these macromolecules: sequential oxidation to the radical cation and dication occurs for all the TTF units, yielding highly-charged species in solution. Macromolecules comprising four and eight TTF units built around a phthalocyanine core are also described. These materials present novel architectures with the key property of multielectron redox activity.
