The attachment of molecular rotary motors containing triethoxysilane functional groups to quartz, silicon and mica surfaces is described. Motors containing silane coupling agents in their structure form stable molecular layers on quartz and silicon surfaces. Motors attached to these surfaces were found to undergo photochemical and thermal isomerization steps similar to those observed in solution. Additionally, successful formation of molecular "carpets" on atomically flat mica extending micrometer-sized length scales is presented. These "carpets" were found to undergo morphological changes upon irradiation with UV-light.
描述了含有三乙氧基硅烷官能团的分子旋转马达在石英、硅和云母表面的附着。结构中含有硅烷偶联剂的马达在石英和硅表面形成稳定的分子层。附着在这些表面上的马达被发现经历了类似于在溶液中观察到的光化学和热异构化步骤。此外，还提出了成功地在原子级平坦的云母上形成延伸至微米级长度的分子“地毯”。这些“地毯”在受到紫外光照射时会发生形态变化。
