A propyltrimethoxysilane-modified 2,2'-bipyridine ligand is synthesized and its acetonitrile solutions are used to prepare monolayers of the molecule on glass surfaces. Absorption and X-ray photoelectron spectroscopy demonstrate that the modified glass surfaces bind Cu(2+) with a 1:1 ratio with respect to the 2,2'-bipyridine moieties under the chosen preparative conditions, producing materials bearing 0.016 μg cm(-2) of copper. Although in trace amounts, the bound Cu(2+) cations exert a significant microbicidal effect against Escherichia coli and Staphylococcus aureus.
合成了一种丙基三甲氧基硅烷改性的 2,2'-联吡啶配体，并将其乙腈溶液用于在玻璃表面制备该分子的单层。吸收和 X 射线光电子能谱表明，在所选的制备条件下，改性玻璃表面以相对于 2,2'-联吡啶部分 1:1 的比例结合 Cu(2+)，生成的材料含有 0.016μgcm(-2)的铜。尽管含量很少，但结合的 Cu(2+)阳离子对大肠杆菌和金黄色葡萄球菌具有显著的杀菌作用。
