设计并合成了具有 N1-丁基尿嘧啶或 N1-苯基尿嘧啶部分的乙撑二硫四硫富瓦烯 (EDT-TTF) 衍生物作为新型氢键电子给体分子，旨在将多重 S...S 相互作用引入由 TTF 核碱基系统组成的氢键结构中。在EDT-TTF衍生物的晶体中，通过pi...pi、多重S...S相互作用和互补双氢键形成二维片状和层状结构。在带有隔离柱的 EDT-TTF-N1-丁基尿嘧啶二元体的四氰基醌二甲烷 (TCNQ) 电荷转移复合物中，通过非共价相互作用构建了电子供体分子的层结构。尿嘧啶部分的正丁基用于分隔供体层之间的空间，从而构建通道结构。无序的 TCNQ 分子位于通道的微孔空间中。 TCNQ配合物在单晶中表现出高电导率(sigmart=2.1 S cm(-1))。
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 pi...pi, multiple S...S interactions, and complementary double hydrogen bonds. In the tetracyanoquinodimethane (TCNQ) charge-transfer complex of the EDT-TTF-N1-butyluracil dyad with a segregated column, a layer structure of the electron-donor molecules was constructed through the noncovalent interactions. The n-butyl group of the uracil moiety served to separate the space between the donor layers, resulting in construction of a channel structure. Disordered TCNQ molecules were located in the microporous space of the channel. The TCNQ complex exhibited high electric conductivity (sigmart= 2.1 S cm(-1)) in a single crystal.
