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

摘要CHE-0647152 Bartels/UC-RiversideThis研究项目，在UC-Riverside的Bartels教授和Marsella教授的实验室进行，解决了表面上设计分子运动的问题。 与定制的动态性能的分子的合成与仔细考虑和表征的分子基板相互作用的组合被用来调查的概念，表现出预定的表面运动的“分子机器”。 在分析和表面化学计划的支持下，该团队通过使用扫描探针显微镜的合成，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。 取代的蒽最初是工作的重点，随着工作原理的发展，分支到其他有希望的吸附物目标。该研究项目的重点是分子的设计，合成和评估，可以作为分子尺度机械的基础。 Bartels和Marsella教授以及他们在加州大学河滨分校的同事正在研究吸附分子的定向运动，这些分子是故意合成的，以利用各向异性吸附物-基质相互作用，导致表面上的定向运动。 这项工作，在分析和表面化学计划的支持下，将为“分子机械”的发展领域提供一些基本的基础。

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".
