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.

在这个项目中开发的新化合物有几个用途。它们可以进一步结合到半导体工业感兴趣的电子和光电材料中。关于电子如何在这些分子中运动的精细细节将使科学家们能够开发出更好的电化学催化剂，用于与可再生能源密切相关的过程，如制氢和二氧化碳固定。此外，任教授和他的学生将开发新的教学模块，以反映普渡大学科学快车项目对可持续化学的浓厚兴趣，该项目向缺乏资源的农村地区的高中提供实验室设备。技术SummaryIn这个项目由化学合成化学部门的项目,同仁堂教授和普渡大学的同事将探索cross-conjugated碳丰富的有机金属化合物的合成化学框架的基础上[M]桥——[M],在[M]是diruthenium物种由N, N '双齿配体或cyclam复合物等三维金属铬、铁和有限公司和桥是geminal-hex-3-ene-1 5-diyne (gem-DEE),或者它的导数。具体目标包括：(1)合成和表征二钌-(gem-DEE)-二钌型化合物和低聚衍生物；(2) M为Cr、Fe或Co的M(cyclam)-(gem-DEE)-M（cyclam）型配合物的合成与表征；(3)阐述跨交叉共轭桥的金属单元之间的电子耦合。这个研究项目将涉及一个由来自不同背景的有才华的研究生和本科生组成的团队。任教授和学生们也将密切参与普渡大学的科学快车项目。
