In this project funded by the Chemical Synthesis Program of the Chemistry Division, Professor Jonathan J. Wilker of the Department of Chemistry at Purdue University will explore the development of methods for the synthesis of carbon rich organometallics based on the combination of Ruthenium and sigma-iso-triacetylene ligands. The past efforts by the carbon rich organometallics community have focused on linear conjugated systems with oligo-yne, oligo-ene and oligo-phenyleneethynylene bridges. The incorporation of sigma-iso-triacetylene requires the development of novel synthetic chemistry. This project may expand our knowledge base about metal-alkynyl compounds. Furthermore, the ubiquitous cross-conjugation manifested by the iso-triacetylene bridge may result in novel physical properties that are absent in the linearly conjugated organometallics, especially the quantum interference effect. The success of the proposed research will enrich the understanding of charge transfer processes in carbon-rich organometallic species and may lead to novel molecular wires and active materials for devices. In addition, this project will provide excellent training for undergraduate students and graduate students, broadening participation through the inclusion of the students from groups historically underrepresented in the sciences. It will also contribute to the existing Alliances for Graduate Education and the Professoriate (AGEP) program at Purdue University.

在这个由化学系化学合成计划资助的项目中，普渡大学化学系的乔纳森·J·威尔克教授将探索开发基于Ru和Sigma-iso-三乙炔配体组合的富碳有机金属化合物的合成方法。富碳有机金属领域过去的努力主要集中在具有低聚炔桥、低聚烯桥和低聚苯乙炔桥的线性共轭体系。引入Sigma-异三乙炔需要发展新的合成化学。这个项目可能会扩大我们关于金属-炔基化合物的知识基础。此外，异三乙炔桥所表现出的无处不在的交叉共轭可能导致线性共轭有机金属中所没有的新的物理性质，特别是量子干涉效应。这项研究的成功将丰富人们对富碳有机金属物种中电荷转移过程的理解，并可能导致新的分子线和器件活性材料的出现。此外，该项目将为本科生和研究生提供极好的培训，通过吸收历史上在科学界代表性不足的群体的学生来扩大参与。它还将为普渡大学现有的研究生教育联盟和教授(AGEP)计划做出贡献。
