项目摘要
We aim to demonstrate that is possible to move vertically and horizontally nano-objects by coupling them to photoactive self assembled monolayers (SAMs) of “light powered molecular cargo lifters”. Molecular rods incorporating azo units and organized in SAMs, undergo efficient photoisomerization, producing cooperative molecular movements able to express a controlled mechanical work. By integrating the expertises of different research groups, we intend to harness the force expressed by azo SAMs, in order to i) move vertically nano-particles sitting on the azo SAMs, and ii) move laterally nano-particles, by sweeping across the surface patterns formed by alternating cis and trans isomers. The patterns are generated by periodic interference gratings. The experimental data will be interpreted with the help of theoretical models. This work can lead to results relevant for short term application in moving nano-objects in three dimensions.
我们的目标是证明,是可能的垂直和水平移动纳米物体耦合到光敏自组装单分子层(SAM)的“光动力分子货物升降机”。分子棒结合偶氮单元和自组装膜组织,进行有效的光异构化,产生合作的分子运动能够表达一个受控的机械功。通过整合不同研究小组的专业知识,我们打算利用偶氮自组装膜所表达的力,以便i)垂直移动位于偶氮自组装膜上的纳米颗粒,以及ii)横向移动纳米颗粒,通过扫过由交替的顺式和反式异构体形成的表面图案。图案由周期性干涉光栅产生。实验数据将在理论模型的帮助下进行解释。这项工作可以导致在三维移动纳米物体的短期应用相关的结果。
