[结构：见正文]合成了一种新型的含尿嘧啶基团的TTF基给体TTF-（1-n-butyluracil-5-yl）（TnbU）。TnbU和TnbU-氰基苯甲酸氢的电荷转移复合物的晶体结构都具有通过尿嘧啶部分和TTF骨架之间的π-堆叠二聚体结构的互补双氢键。此外，TnbU-TCNQ电荷转移复合物显示出高的电导率，其基础是伴随着氢键相互作用的部分电荷转移，这在IR，电子光谱和电导率的测量方面得到了证实。
[structure: see text] A novel TTF-based donor with a uracil moiety, TTF-(1-n-butyluracil-5-yl) (TnbU), was synthesized. Crystal structures of both TnbU and the charge-transfer complex of TnbU-hydrogen cyananilate possess complementary double hydrogen bonds through uracil moieties and pi-stacking dimer structures between TTF skeletons. Furthermore, the TnbU-TCNQ charge-transfer complex shows a high electrical conductivity underlying the partial charge-transfer accompanied by a hydrogen-bonding interaction, which was substantiated in terms of the measurements of the IR, electronic spectra, and conductivity.
