WIRE-LIKE and GYROSCOPE-LIKE ORGANOMETALLIC COMPLEXES

在这个由化学系化学合成计划资助的项目中，德克萨斯A M大学化学系的John Gladysz教授将探索两种类型的有机金属分子器件的合成和详细的化学和物理表征，线状和陀螺状复合物。前者的特征在于跨越过渡金属片段的sp-杂化碳链。陀螺仪的特征是MLn碎片被两个反式磷原子束缚，这些原子被三个烃链束缚。大环双桥头双膦在一定条件下可以解络合，经历一个迷人的动态过程，通过这个过程它们将自己从内到外翻转，并协同地构成一些线状化合物的有希望的配体。宏观器件的小型化代表了社会不断追求更小、更强大和更有效的消费产品如移动的电话、计算机、以及私人和商用车辆。分子导线是实现分子电路和电子学的必要条件。该项目将为本科生和研究生同事以及博士后提供广泛深入的专业培训。他们将获得尖端的实验室技能，并发展他们的写作和口头表达能力。

In this project funded by the Chemical Synthesis Program of the Chemistry Division, Professor John Gladysz of the Department of Chemistry at Texas A&M University will explore both the synthesis and detailed chemical and physical characterization of two types of organometallic molecular devices, wire-like and gyroscope-like complexes. The former features sp-hybridized carbon chains that span transition metal fragments. The gyroscopes feature MLn fragments encaged by two trans-phosphorus atoms that are tethered by three hydrocarbon chains. The macrocyclic dibridgehead diphosphines can be decomplexed under certain conditions, undergo a fascinating dynamic process by which they turn themselves inside-out, and synergistically constitute promising ligands for some of the wire-like compounds.The miniaturization of macroscopic devices represents one of the greatest challenges as society continually strives for smaller and more powerful and efficient consumer products such as mobile phones, computers, and personal and commercial vehicles. Molecular wires are necessary for the realization of molecular circuits and electronics. This project will provide broad in-depth professional training for undergraduate and graduate student coworkers, as well as postdoctorals. They will acquire cutting edge laboratory skills and develop their writing and oral presentation capabilities.
