Guided Motion at Surfaces: Exploratory Research towards Molecular-Scale Machinery

这项研究项目在加州大学河滨分校的巴特尔斯教授和马塞拉教授的实验室中进行，解决了表面上设计的分子运动的问题。具有量身定做的动态性质的分子的合成与分子底物相互作用的仔细考虑和表征相结合，被用来研究显示预定表面运动的“分子机器”的概念。在分析和表面化学计划的支持下，该团队利用扫描探针显微镜，通过合成、吸附和表征之间的系统相互作用，探索定向表面“步行者”和可能的“载体”的发展。取代菲最初是这项工作的重点，随着工作原理的发展，它将转移到其他有希望的吸附目标。这项研究项目专注于分子的设计、合成和评估，这些分子可以作为分子尺度机械的基础。加州大学河滨分校的Bartels和Marsella教授及其同事正在研究被吸附分子的定向运动，这些分子被故意合成，以利用各向异性吸附-底物相互作用，导致表面上的定向运动。在分析和表面化学计划的支持下，这项工作将为“分子机械”的发展领域提供一些基本的基础工作。

AbstractCHE-0647152Bartels/UC-RiversideThis research project, carried out in the laboratories of Professor Bartels and Professor Marsella at UC-Riverside, addresses the question of designed molecular motion on surfaces. The combination of the synthesis of molecules with tailored dynamic properties with careful consideration and characterization of the molecule substrate interaction is used to investigate the concept of "molecular machines" exhibiting pre-determined surface motion. With the support of the Analytical and Surface Chemistry Program, this team explores the development of directional surface "walkers" and possible "carriers" by a systematic interplay between synthesis, adsorption, and characterization using scanning probe microscopy. Substituted anthracenes are the focus of the work initially, branching to other promising adsorbate targets as the principles of the work develop. This research project focuses on the design, synthesis, and evaluation of molecules that could serve as the basis for molecular scale machinery. Professors Bartels and Marsella, and their coworkers at UC-Riverside, are examining the directional motion of adsorbed molecules that have been purposely synthesized to take advantage of anisotropic adsorbate-substrate interactions, leading to directional motion on the surface. This work, with the support of the Analytical and Surface Chemistry Program, will provide some of the fundamental groundwork for the developing area of "molecular machinery".
