作为很强的有机电子给体,四硫富瓦烯能够在低电位被可逆氧化,失去一个或两个电子生成相应的正一价阳离子自由基或正二价阳离子．近年来它在众多领域显示出日益重要的作用．本论文设计合成了一系列具有D-π-A和A-π-D-π-A结构的四硫富瓦烯 (TTF)衍生物,系统研究了它们在基态发生分子内电荷转移的可能,并利用外界刺激改
As a strong organic electron donor, tetrathiafulvalene can be reversibly oxidized at low potential, losing one or two electrons to generate the corresponding positive monovalent cation radicals or positive divalent cations. In recent years it has shown an increasingly important role in many fields. In this thesis, a series of tetrathiafulvalene (TTF) derivatives with D-π-A and A-π-D-π-A structures have been designed and synthesized, and their potential for intramolecular charge transfer in the ground state has been systematically investigated.
