Professor Don Tilley, Department of Chemistry, University of California at Berkeley is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program to prepare and investigate silicon-based compounds and materials that possess chemical, structural and electronic properties making them potentially suitable for diverse scientific and technological applications. The principal strategy employed is to use transition metal reagents and catalysts that has resulted (through the years) in the production of a wealth of important carbon-based products. In the present instance, efforts will be focussed towards making "analogous" but silicon-based materials by examining first the fundamental transformations of silicon species (e.g. silylene, SiR2; silenes, R2Si=SiR'2, etc..particularly LnM=SiR2 systems) at the metal centers, and subsequently by exploring the structures, bonding, and structure-reactivity relationships in these species. Professor Tilley has been a leader in developing synthetic methodologies in metal-silicon compounds. Efforts will also be expended towards targeting new pi-systems containing unsaturated silicon and germanium atoms in the hope that these new systems will provide some unusual electronic properties that might give way to conjugated macromolecules incorporating double bonds in silicon and germanium.

加州大学伯克利分校化学系Don Tilley教授由无机化学、生物无机化学和金属有机化学计划支持，制备和研究具有化学、结构和电子性质的硅基化合物和材料，使其具有潜在的适用于各种科学和技术应用的能力。所采用的主要战略是使用过渡金属试剂和催化剂，这些试剂和催化剂(多年来)已导致大量重要的碳基产品的生产。在目前的情况下，将集中精力通过首先检查硅物种(例如，硅烯、Si2；硅烯、R2Si=SIR‘2等)在金属中心的基本转变，特别是LNM=Si2体系，以及随后通过探索这些物种中的结构、成键和结构-反应性关系，来努力制造类似的但基于硅基的材料。蒂利教授在开发金属硅化合物的合成方法方面一直处于领先地位。还将努力瞄准含有不饱和硅和锗原子的新的pi体系，希望这些新体系将提供一些不寻常的电子性质，这些性质可能会让位于含有硅和锗双键的共轭大分子。
