This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Dr. Clifford P. Kubiak at the University of California at San Diego to develop molecular probes for picosecond chemical dynamics based on redox coupled mixed-valent states; and molecular electronic devices that exhibit electronic bistability and picosecond switching times. The development of ultrafast inorganic ground states as dynamical probes provides a simple spectroscopic method based on molecules that can be designed to interrogate many different environments where knowledge of the local dynamics is important. In principle, ultrafast mixed valence states can be used to probe the dynamics of any process that can be coupled to electron transfer. Ultrafast inorganic ground states as molecular devices will be investigated based on the paradigm provided by "mixed valence isomers". Success in this research would impact the broader scientific and engineering communities involved in electronic device technologies, as the mixed valence isomers under study can switch between stable states at the rate of one trillion times per second or roughly a thousand fold increase in clock speed compared to current technology. Study of these systems will likely influence chemical, physical, and engineering issues that will bring molecular electronic devices into the mainstream. The project will involve undergraduate men and women through the UCSD undergraduate research mentoring program. The project will interface with existing outreach programs at UCSD to recruit underrepresented groups into Ph. D. programs.

该奖项属于无机、生物无机和有机金属化学项目，支持加州大学圣地亚哥分校的 Clifford P. Kubiak 博士的研究，开发基于氧化还原耦合混合价态的皮秒化学动力学分子探针；以及具有电子双稳态和皮秒切换时间的分子电子器件。超快无机基态作为动力学探针的发展提供了一种基于分子的简单光谱方法，可以设计用于询问许多不同的环境，在这些环境中，局部动力学的知识很重要。原则上，超快混合价态可用于探测与电子转移耦合的任何过程的动力学。作为分子器件的超快无机基态将基于“混合价异构体”提供的范式进行研究。这项研究的成功将影响涉及电子设备技术的更广泛的科学和工程界，因为正在研究的混合价异构体可以以每秒一万亿次的速度在稳定状态之间切换，或者与传统的相比，时钟速度增加大约一千倍。当前技术。 对这些系统的研究可能会影响化学、物理和工程问题，从而使分子电子器件成为主流。该项目将通过加州大学圣地亚哥分校本科生研究指导计划让男女本科生参与。该项目将与加州大学圣地亚哥分校现有的外展项目相结合，招募代表性不足的群体进入博士项目。
