The article concerns a novel functional material in the form of thin film: vertically aligned mesoporous silica layer precisely functionalized by nickel chloride molecules. The functional units are placed exclusively inside silica walls, where they are chelated by cyclam (1,4,8,11-tetraazacyclotetradecane) molecules. The synthesis routes, based on a self-assembly approach, resulted in materials with the assumed molecular structure. The microscopic studies of the silica matrices structure confirmed that tetrasilylated cyclam did not perturb the formation of porous silica films. Vibrational spectroscopy showed incorporation of the cyclam inside silica structure. In turn, the EPR spectroscopy confirmed, that nickel dichloride was chelated by cyclam molecules, which resulted in a homogeneous distribution of functional nickel-containing groups.

该文章涉及一种薄膜形式的新型功能材料：由氯化镍分子精确功能化的垂直排列的介孔二氧化硅层。这些功能单元仅放置在二氧化硅壁内部，在此处它们被环am（1,4,8,11-四氮杂环十四烷）分子螯合。基于自组装方法的合成路线产生具有假定分子结构的材料。二氧化硅基质结构的显微镜研究证实，四甲硅烷基化的环己酰胺不会干扰多孔二氧化硅膜的形成。振动光谱表明硅酮结构中掺入了Cyclam。相应地，EPR光谱证实，二氯化镍被cyclam分子螯合，导致功能性含镍基团的均匀分布。
