Some TTF vinylogues 1 containing phenyl groups at the vinyl positions were synthesized. The redox properties were investigated by cyclic voltammograms, showing that they are strong electron donors and the Coulomb repulsion is decreased in the dication states. Some of the donors afforded their dication salts as single crystals by electrochemical oxidation or the reaction with CuCl2. X-ray structure analysis
合成了一些在乙烯基位置含有苯基的TTF乙烯基化合物1。通过循环伏安图研究了氧化还原性质,表明它们是强电子给体,并且在指示状态下库仑排斥力降低。一些供体通过电化学氧化或与CuCl 2的反应提供了单晶形式的它们的指示盐。X射线结构分析表明,指示剂分子具有带有平面TTF乙烯基单体和扭曲的苯基的结构。为了避免苯基的空间相互作用,晶体结构是不寻常的。
