Novel Carbon Rich Organometallics based on iso-Triacetylene: Effects of Cross Conjugation

在这个由化学系化学合成项目资助的项目中，普渡大学化学系的Jonathan J. Wilker教授将探索基于钌和σ-异三乙炔配体组合的富碳有机金属化合物的合成方法的发展。 富碳有机金属化合物社区过去的努力集中在具有低聚炔、低聚烯和低聚亚苯基乙炔桥的线性共轭体系上。 引入σ-异三乙炔需要开发新的合成化学。 该项目可以扩展我们对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会导致线性共轭有机金属化合物所不具备的新的物理性质，特别是量子干涉效应。该研究的成功将丰富对富碳有机金属物种中电荷转移过程的理解，并可能导致新型分子导线和器件活性材料。 此外，该项目还将为本科生和研究生提供出色的培训，通过纳入历史上在科学领域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。

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.
