Non Technical SummaryThe new compounds developed in this project serve several purposes. They can be further incorporated into electronic and opto-electronic materials that are of interest to the semiconductor industry. Exquisite details about how electrons move around within these molecules will enable scientists to develop better electrochemical catalysts for processes closely related to renewable energy such as hydrogen production and carbon dioxide fixation. In addition, Professor Ren and his students will develop new teaching modules that reflect the heightened interest in sustainable chemistry for Purdue's Science Express program, which delivers laboratory equipment sets to high schools in the rural areas that lack resources. Technical SummaryIn this project funded by the Chemical Synthesis Program of the Chemistry Division, Professor Tong Ren and coworkers at Purdue University will explore the synthetic chemistry of cross-conjugated carbon rich organometallics based on the frameworks of [M]-bridge-[M], where [M] is either a diruthenium species supported by N,N'-bidentate ligands, or cyclam complexes of 3d metals such as Cr, Fe and Co, and the bridge is either geminal-hex-3-ene-1,5-diyne (gem-DEE), or its derivatives. Specific aims include (1) the synthesis and characterization of diruthenium-(gem-DEE)-diruthenium type compounds and oligomeric derivatives; (2) the synthesis and characterization of M(cyclam)-(gem-DEE)-M(cyclam) type complexes with M as Cr, Fe or Co; and (3) the elaboration of electronic couplings between metal units across the cross-conjugated bridge. This research project will involve a team of talented graduate and undergraduate students from diverse backgrounds. Professor Ren and students will also be intimately involved with Purdue's Science Express program.

非技术摘要该项目中开发的新化合物有多种目的。它们可以进一步纳入半导体行业感兴趣的电子和光电材料中。 有关电子如何在这些分子中移动的精美细节将使科学家能够开发出与可再生能源（例如氢生产和二氧化碳固定）密切相关的过程的更好的电化学催化剂。此外，Ren教授和他的学生将开发新的教学模块，以反映对普渡大学科学快递计划的可持续化学兴趣，该计划为缺乏资源的农村地区的高中提供实验室设备。 Technical SummaryIn this project funded by the Chemical Synthesis Program of the Chemistry Division, Professor Tong Ren and coworkers at Purdue University will explore the synthetic chemistry of cross-conjugated carbon rich organometallics based on the frameworks of [M]-bridge-[M], where [M] is either a diruthenium species supported by N,N'-bidentate ligands, or cyclam complexes of 3d metals such as Cr, Fe和CO，桥是Geminal-Hex-3-Ene-1,5-Diyne（Gem-Dee）或其衍生物。具体目的包括（1）diruthenium-（gem-dee） - 杜伦类型化合物和寡聚衍生物的合成和表征； （2）M（Cyclam） - （Gem-Dee）-M（Cyclam）型复合物的合成和表征与M作为Cr，Fe或Co； （3）在跨缀合的桥梁上的金属单元之间详细说明电子耦合。该研究项目将涉及一支来自不同背景的才华横溢的毕业生和本科生。 Ren教授和学生还将与Purdue的Science Express计划密切相关。
