AbstractCHE-0555696Hipps/Washington StateWith the support of the Analytical and Surface Chemistry Program, Professor Hipps and his colleagues at Washington State University are carrying out further development of the novel spectroscopic technique Orbital Mediated Tunneling Spectroscopy (OMTS). This method, reduced to practice by Hipps, provides fundamental electronic structure information about single molecules adsorbed on solid surfaces. Phthalocyanines, porphyrins, and polyacenes adsorbed on metal and semiconductor substrates are being examined. Such site specific molecular level information is crucial to developing an understanding of the operation, and the development of the design principles for, organic electronic devices. This research project provides an excellent training platform for students interested in this important interdisciplinary area. Researchers in the Hipps group at Washington State University are using a novel technique known as Orbital Mediated Tunneling Spectroscopy to examine the electronic properties of adsorbed organic molecules one molecule at a time. The fundamental information gained from these studies will help to design the next generation of molecular electronic devices. This interdisciplinary work also serves as an excellent training ground for a broad range of graduate and undergraduate students.

Hipps/华盛顿州在分析和表面化学计划的支持下，华盛顿州立大学的Hipps教授和他的同事们正在进一步开发新的光谱技术轨道介导隧道光谱(OMTS)。这种方法被Hipps简化为实践，提供了关于吸附在固体表面的单分子的基本电子结构信息。金属和半导体衬底上吸附的酞菁、卟啉和聚并苯正在被检测。这种特定部位的分子水平信息对于理解有机电子器件的操作和开发设计原则至关重要。这一研究项目为对这一重要跨学科领域感兴趣的学生提供了一个极好的培训平台。华盛顿州立大学希普斯小组的研究人员正在使用一种名为轨道介导隧道光谱的新技术，一次检测一个分子的吸附有机分子的电子性质。从这些研究中获得的基本信息将有助于设计下一代分子电子器件。这项跨学科的工作也是广泛的研究生和本科生的极好的培训基地。
