合成了一种新的手性四硫富瓦烯(TTF)衍生物和相关的甲硅烷基取代的1,3-二硫基-2-(thi)one化合物,并通过1 H NMR,13 C NMR,MS和IR光谱进行了表征。甲硅烷基取代的1,3-二硫醇-2-酮的单晶结构显示出化合物中五元环部分的高度共轭。通过循环伏安法研究了新型TTF衍生物的电化学性质,结果表明手性TTF衍生物的供电子能力与BEDT-TTF相似。该Δ Ë新的TTF衍生物的值小于TTF和BEDT-TTF的值,表明在化学氧化还原状态下库仑排斥力降低。证明了在新的供体和电子受体2,3-二氯-5,6-二氰基-1,4-苯醌(DDQ)之间形成了电荷转移(CT)配合物。
Enantiomerically pure dithiolene complexes NBu4[Ni[(R,R)-diotte)2] and NBu4[Ni((S,S)-diotte]2] (diotte2- = a 1,3-dioxolane-tetrathiaethylene), were prepared from the corresponding enantiomers of a diotte2- precursor. The structure of the precursor was solved by single-crystal X-ray analysis; desulfurization afforded a novel tetrathiafulvalene derivative. Combination of the complex monoanion with the enantiomers
cyclic voltammetry and the results indicated that the electron-donating ability of the chiral TTF derivative was similar to that of BEDT-TTF. The ΔE value for the new TTF derivative was smaller than those for TTF and BEDT-TTF, indicative of decreased Coulombic repulsion in the dicationic redox state.
