摘要: 合成了2个含3个四硫代富瓦烯单元的化合物,给出了它们的核磁共振氢谱、质谱、紫外吸收光谱及元素分析数据。用循环伏安法测定了它们的氧化还原电位,并将其与仅含1个或2个四硫代富瓦烯单元的化合物的氧化还原电位比较。发现随着分子内共轭程度的增加,分子内的库仑斥力也随之降低。

Abstract: Two polynuclear tetrathiafulvalene (TTF) derivatives, which contained three TTFsub-units, were synthesized. Their 1HNMR,13CNMR, MS, and UV absorption spectra as well as cyclic voltammograms (CV) were given. The CV behaviour of the compounds was compared with that of corresponding TTFderivatives containing one or two TTF sub-units. It indicated that the coulombic repulsion in the former was lower than that in the latter, because a conjugation degree in the former was longer than in the latter.
