摘要: 提供了一种合成噻吩基和呋喃基四硫富瓦烯(TTF)的方法,并用其合成了3种未见文献报道的噻吩基TTF(Ⅶa,Ⅶb,Ⅶc)和2种呋喃基TTF(Ⅶdl,Ⅶd2).研究了这些化合物的循环伏安行为及有关电化学性质,制得了一种Ⅶb与TCNQ反应生成的电荷转移络合物,讨论了噻吩基TTF和呋喃基TTF在产物构型和电化学性质方面的差别.

Abstract: Amethod is proposed to synthesize thienyl and furyl tetrathiafulvalenes (TTF).Three new thienyl-TTF (Ⅶ a-c) and two furyl-TTF (Ⅶ d1-d2) were prepared by the method.The electrochemical property of the five TTFderlvatives prepared was studiedo by cyclic voltammetry.It was found that the value of E1/2 decreased when the electron-donating group was in the thienyl ring of thienyl-TTF, the value of E1/2 increased when electron-attracting groups was in the thienyl ring of thienyl-TTF.No peak appeared on the figure of cyclic valtammetry for furyl-TTF.The potential of reduction was higher than that of oxidation, the electrlc current of the highest peak increased by 50 times than the second peak in the figure of square wave voltarnmogram.The reason why thienyl-TTFderivatives only gave trans-isomers and furyl-TTFgave cis and trans-isomers was discussed.Charge-transfer complex of Ⅶb with TCNQ (1: 1) was also prepared.

Key words: Thienyltetrathiafulvalene, Furyltetrathiafulvalene, Cyclic voltammogram, Charge-transfer complex
