Molecular Photonic Materials

化学，结构，动力学和机制计划支持约翰霍普金斯大学的Gerald Meyer教授的工作，对与太阳能燃料产生相关的分子半导体界面的光引发键断裂和键形成反应的机制进行基础研究。 拟议的研究将具体集中在半导体界面的分子的电子转移行为的量化和这种行为与电荷转移动力学相关的金属配体和碳-碳键的形成。 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。 提出的分子和材料将使人们能够解决长期存在的基本界面科学问题，这些问题与太阳能转换的分子细节有关，这在二十年前是不可能的。 通过参与这项基础研究，本科生和研究生水平的学生将接受分子半导体界面动力学和热力学表征的强化培训。 该建议将培养跨学科领域的学生，特别关注分子配位化学，催化，光化学和光电化学。 这些研究的结果被设想为有一天能够实现合理的分子水平设计的集成材料，能够收集阳光，矢量电荷分离和多电子转移催化，以形成有用的燃料。

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.
