Development of surface functionalization methods by the use of molecular connecting modules

近年来，从制备高功能金属材料的角度出发，对金属表面进行分子水平修饰的方法得到了广泛的关注。在这项研究中，我们开发了一种利用环三（螺硼酸酯）s （TB）对金属底物和金属纳米颗粒进行表面改性的新方法。为了实现结核在金属表面的固定化，我们在结核表面引入了乙酰硫基等锚定基团。这些结核杆菌已被证明是金纳米颗粒稳定的保护剂，尽管结核杆菌在金属基质上的固定仍在进行中。

Recently, much attention has been paid to the development of the method for molecular level modification of metal surfaces in the viewpoint of the preparation of highly functional metallic materials. In this study, we have developed the new surface-modification method for metal substrates and metal nanoparticles by the use of cyclic tris(spiroborate)s (TB). To realize the immobilization of TB onto metal surfaces, we have introduced anchor group such as acetylthio group to TB. These TBs have been proven to act as the protective agents for the stabilization of gold nanoparticles, although fixation of TBs onto the metal substrates was still in progress.
