Reactive scattering of small molecules from metal phthalocyanine surfaces is used to probe chemisorption dynamics on model organic surfaces. The distinct roles of organic and metal center on the adsorption dynamics is examined in this research project supported by the Analytical and Surface Chemistry Program. Professor Kummel and his coworkers at the University of California-San Diego use a combination of molecular beam scattering tools and scanning tunneling microscopy to examine the dynamics of small molecule adsorption on these model organic surfaces. Bonding sites are examined using STM and STS, chemisorption mechanism is probed using reactive scattering molecular beam methods, and density functional calculations are carried out to model the experimental results. Understanding how small molecules adsorb and react on organic and organometallic surfaces is the goal of this research project supported in the Analytical and Surface Chemistry Program. Using a combination of experimental probes, particularly molecular beam scattering and scanning probe microscopy, the detailed dynamics of small molecules interacting with phthalocyanine surfaces are examined. This fundamental information may have applicability in the design of molecule specific sensors and organic molecule electronics.

小分子在金属酞菁表面的反应散射被用来探测模型有机表面上的化学吸附动力学。 本研究由分析与表面化学计划资助，探讨有机中心与金属中心对吸附动力学的不同作用。 加州大学圣地亚哥分校的Kummel教授和他的同事使用分子束散射工具和扫描隧道显微镜的组合来研究这些模型有机表面上小分子吸附的动力学。 键合位点进行了检查，使用STM和STS，化学吸附机制探测使用反应散射分子束方法，并进行密度泛函计算模拟实验结果。了解小分子如何在有机和有机金属表面吸附和反应是分析和表面化学计划支持的本研究项目的目标。 使用实验探针的组合，特别是分子束散射和扫描探针显微镜，与酞菁表面相互作用的小分子的详细动力学检查。 这些基本信息可能在分子特异性传感器和有机分子电子学的设计中具有应用价值。
