项目摘要

The Emslie research program is focused on the development of unique ligands and ligand combinations to advance the fields of organometallic catalysis and Atomic Layer Deposition (ALD), and to generate new knowledge and understanding. Under this umbrella, the three research themes in this proposal are:***(1) Lewis-acid appended transition metal complexes for applications in cooperative catalysis, with a focus on transformations involving alkenes, CO and CO2,***(2) Highly rigid pincer ligands for the synthesis of thermally robust rare earth and actinide olefin polymerization catalysts, and alkane s-complexes relevant to C-H bond activation, and***(3) New organometallic precursors and reactivities for Atomic Layer Deposition (ALD) of metal films.***Each of the above topics combines fundamental/exploratory organometallic chemistry with at least one target application that has not yet been realized, and is of high current importance:***The Lewis acid-appended transition metal complexes in research area 1 offer new possibilities for the development of challenging catalytic transformations involving CO and CO2. These transformations are economically desirable, and in the case of CO2, they would also be environmentally beneficial.***The rare earth metal catalysts targeted in area 2 are designed to exhibit high thermal stability, as required for industrial application. Catalysts based on the rare earth metals exhibit unique and desirable polymerization capabilities, such as facile copolymerization of ethylene with styrene, cyclic olefins, and dienes, and ethylene co-polymerization with very high levels of a-olefin incorporation. However, industrial use of these catalysts has typically been prevented by low thermal stability.***The metal-alkane complexes to be prepared in research area 2 feature a metal center located in a rigidly defined hydrophobic pocket. These complexes will provide valuable chemical insight relevant to C-H activation of highly unreactive alkanes, contributing either directly or indirectly to the development of future alkane functionalization reactivity.***The organometallic ALD precursors that are the focus of the research in area 3 are designed to exhibit a unique combination of high volatility, high thermal stability, and high reactivity with selected organometallic reagents. As such, they are expected to allow the development of the first methods for ALD of highly electropositive metals, which will be required to enable continued miniaturization of the basic components of microprocessors and memory devices.**

EMSLIE研究计划的重点是开发独特的配体和配体组合，以推动有机金属催化和原子层沉积（ALD）的领域，并在此伞上产生新的知识和理解。：***（1）在合作催化，CO和CO2中应用的Lewis-Acid附加过渡，***（2）高度刚性的钳子配体，用于合成热稳健的稀土和actacinide olefin olefin聚合聚合物聚合的statalyst statalyst statalyst statalyst catatalyst catatalyst catatalyst，用于原子层层stodosition层的无原子层降低。金属膜的（ALD）***上述每个主题都结合了基本 /探索性有机金属化学和至少一个尚未实现的目标涉及CO和二氧化碳的特征是经济的理想选择，而在2号区域的二氧化碳催化剂的情况下，基于稀有金属的催化剂所需的高热稳定性。然而，诸如乙烯的同时化，催化剂的催化剂通常是由低稳定的催化剂高度高度不反应性烷烃高度高度相关的化学洞察力，可以促进未来的烷烃功能化的脱翼。预计他们将允许开发高度阳性金属的ALD的第一个方法，这将被要求持续小型化微处理器和存储器设备的基本组件。** **
