Tetrathiafulvalene (TTF) has been one of the most well-studied heterocyclic compounds since the discovery of the electrical conductivity of its charge-transfer complexes in the early 1970s. As the half unit of TTF, 1,4-dithiafulvene (DTF) presents an excellent organic electron donor and hence has been widely utilized as a functional molecular building block in the design of advanced organic electronic and optoelectronic materials. In the early years of DTF chemistry, research efforts were mainly focused on the development of π-extended TTFs as well as related donor/acceptor (D/A) functionalized π-conjugated systems. Meanwhile, studies dealing with the redox-activity and reactivity of DTF have also progressed significantly over the past few decades. With the growing understanding of the fundamental properties of DTF, the past ten years have witnessed significant advances in the development of DTF-based organic π-conjugated materials and related optoelectronic devices with novel properties and enhanced performances. This review is aimed at reviewing the new chemical properties and reactivities of DTF disclosed in the recent literature as well as highlighting the molecular design, synthesis, and application of state-of-the-art DTF-containing organic π-conjugated materials.

二硫富烯酰基官能化的有机共轭材料的最新进展

自从1970年代初发现其电荷转移复合物的电导率以来，四硫富瓦烯（TTF）一直是研究最深入的杂环化合物之一。1,4-二硫富烯（DTF）作为TTF的半单元，具有出色的有机电子给体，因此已被广泛用作高级有机电子和光电材料设计中的功能分子构件。在DTF化学的早期，研究工作主要集中在π扩展TTF以及相关供体/受体（D / A）功能化π共轭体系的开发上。同时，在过去的几十年中，有关DTF的氧化还原活性和反应性的研究也取得了显着进展。随着人们对DTF基本属性的了解不断加深，在过去的十年中，基于DTF的有机π共轭材料和具有新颖特性和增强性能的光电器件的开发取得了重大进展。这篇综述旨在综述最近文献中公开的DTF的新化学性质和反应性，并重点介绍分子设计，合成和最新的含DTF的有机π共轭材料的应用。
