3-benzodithioles as candidates for new electron donors. The oxidation potential of monosilyl-substituted 1,3-benzodithiole was found to be significantly less positive than that of the parent 1,3-benzodithiole. The introduction of the second silyl group caused further decrease of the oxidation potential. Compounds composed of two 1,3-benzodithiole units linked by a silyl group were also synthesized. These
分子轨道计算表明,在 1,3-二硫醇的 2-位引入甲硅烷基会导致电离电位显着降低,并且 2-甲硅烷基-1,3-二硫醇充当伪 π 电子系统。甲硅烷基还可用作连接 π 电子系统以实现人工堆叠的桥梁。这些概念引导我们设计和合成甲硅烷基取代的 1,3-苯二硫醇作为新电子供体的候选物。发现单甲硅烷基取代的 1,3-苯二硫醇的氧化电位明显低于母体 1,3-苯二硫醇的氧化电位。第二个甲硅烷基的引入导致氧化电位进一步降低。还合成了由两个由甲硅烷基连接的 1,3-苯并二硫醇单元组成的化合物。这些显示出与相应单体化合物相当的氧化电位。发现甲硅烷基取代对 1,3-二硫醇的 2-位的影响大于...
