The Chemical, Structure, Dynamics, and Mechanism program supports work by Professor Gerald Meyer at Johns Hopkins University to carry out fundamental studies on the mechanisms of photo-initiated bond-breaking and bond-forming reactions at molecular-semiconductor interfaces relevant to solar fuels generation. Proposed studies will specifically focus on quantification of the electron transfer behavior of molecules at semiconductor interfaces and correlation of this behavior with charge transfer kinetics relevant to the formation of metal-ligand and carbon-carbon bonds. The proposed studies are fundamental in nature, but are directly relevant to the development of efficient photocatalytic materials. The molecules and materials proposed will enable one to address long-standing fundamental interfacial science questions relevant to solar energy conversion in molecular detail that was not possible even twenty years ago. Through participation in this fundamental research, students at the undergraduate and graduate level will receive intensive training in characterization of the kinetics and thermodynamics of molecular-semiconductor interfaces. This proposal will train students in interdisciplinary areas with particular focus on molecular coordination chemistry, catalysis, photochemistry, and photoelectrochemistry. Results from these studies are envisioned to one day enable the rational molecular-level design of integrated materials capable of harvesting sunlight, vectorial charge separation, and multi-electron transfer catalysis to form useful fuels.

化学、结构、动力学和机理项目支持约翰·霍普金斯大学杰拉尔德·迈耶教授的工作，对与太阳能燃料发电相关的分子半导体界面上的光引发断键和成键反应的机制进行基础研究。 拟议的研究将特别关注半导体界面分子电子转移行为的量化以及该行为与与金属-配体和碳-碳键形成相关的电荷转移动力学的相关性。 所提出的研究本质上是基础性的，但与高效光催化材料的开发直接相关。 所提出的分子和材料将使人们能够解决与分子细节上的太阳能转换相关的长期存在的基础界面科学问题，这在二十年前是不可能的。 通过参与这项基础研究，本科生和研究生将接受分子半导体界面动力学和热力学表征方面的强化培训。 该提案将培训跨学科领域的学生，特别关注分子配位化学、催化、光化学和光电化学。 这些研究的结果预计有一天能够对能够收集阳光、矢量电荷分离和多电子转移催化的集成材料进行合理的分子水平设计，以形成有用的燃料。
