摘要
TTN(TTN=1,4,5,8-Tetrathianaphthalene)是四硫富瓦烯(TTF)的异构体,是组成有机自由基离子盐导体潜在的給体分子。我们以TTN为核心骨架,通过在其外围稠合芳香体系来得到扩展的带状分子。基于我们实验室开发的新型的Cu催化的Modified-Ullmann C-S键偶联的新方法~([1][2]),我们以(TBA)_2[Zn(DMIT)_2]化合物为原料,通过两次Cu催化的C-S键偶联反应,成功高效的实现了一系列芳基稠合的TTN衍生物的合成。研究表明,TTN衍生物的第一氧化还原电位远高于相应的TTF衍生物,为弱的电子給体。凝聚态结构表明,所有TTN分子呈椅式构型,中心C_2S_4与外围芳环折叠。我们功制备了一系列TTN衍生物和富勒烯(C_(60)/C_(70))分子的共结晶复合物。复合物中,富勒烯分子形成了紧密的二维堆积。
TTN is a structural isomer of tetrathiafulvalene,which are of interest as potential donor components in organic radical ion salt conductor.Using readily available zinc-thiolate complex(TBA)_2[Zn(DMIT)_2]as starting material,a two-fold Cu-catalyzed C-S coupling afforded a series of aryl-fused TTNs in good yield.Compared with TTF,these TTNs are weak donor molecules as proved by electrochemical investigation.Single crystal structure analysis proves mat these TTNs mainly take the chair conformation.Further investigation indicates that these TTNs can host fullerene molecules.
