Ethylenedithiotetrathiafulvalene (EDT-TTF) derivatives with N1-butyluracil or N1-phenyluracil moiety were designed and synthesized as new hydrogen-bonded electron-donor molecules with the aim of introducing multiple S···S interactions into the hydrogen-bonded structures composed of the TTF−nucleobase systems. In the crystals of the EDT-TTF derivatives, two-dimensional sheet and layer structures were formed through π···π
设计并合成具有N 1-丁基尿嘧啶或N 1-苯基尿嘧啶部分的乙二硫四硫富富烯烯(EDT-TTF)衍生物,作为新的氢键电子给体分子,目的是将多个S···S相互作用引入所组成的氢键结构中TTF-nucleobase系统的。在EDT-TTF衍生物的晶体中,通过π··π,多个S···S相互作用和互补的双氢键形成二维片层结构。在具有分离柱的EDT-TTF- N 1-丁基尿嘧啶二聚体的四氰基喹二甲烷(TCNQ)电荷转移复合物中,电子供体分子的层结构是通过非共价相互作用而构建的。这尿嘧啶部分的正丁基用于分隔供体层之间的空间,从而形成通道结构。无序的TCNQ分子位于通道的微孔空间中。TCNQ复合物在单晶中表现出高电导率(σrt = 2.1 S cm - 1)。
