The synthesis of organic thiosulfates, up to 10 nm in length, which were tailored for generating artificial monomembranes on gold surfaces by electrochemically initiated deposition, was accomplished. (E)-3-(4-Hydroxyphenyl)acrylic acid (4-hydroxy cinnamic acid) was employed as aromatic head group and (C10H20-O-)n (n = 1, 3, 5, 7) building blocks were attached. The synthetic procedure comprises a series of nucleophilic substitutions under carefully defined conditions. Extended purification is crucial for eliminating non-reacted starting materials.
成功合成了长度可达10纳米的含硫有机硫代硫酸盐,这些化合物经过定制,用于通过电化学引发的沉积过程在金表面生成人工单层膜。采用了(E)-3-(4-羟基苯基)丙烯酸(4-羟基肉桂酸)作为芳香头部基团,并结合了(C10H20-O-)n(n=1, 3, 5, 7)结构单元。合成过程包括在精心界定的条件下进行的一系列亲核取代反应。延长纯化步骤对于去除未反应的原始材料至关重要。
