The Chemical Structure, Dynamics and Mechanisms Program of the Division of Chemistry supports the research of Professor James A. Phillips and undergraduate research students at the University of Wisconsin - Eau Claire (UWEC). Phillips and his students will extend their previous experimental and theoretical research on a novel class of Lewis acid-base complexes that undergo significant structural changes between various chemical environments (i.e., when they move from the gas-phase to a solution). Their primary experimental technique is low-temperature infrared spectroscopy, which is applied to two types of sample environments for these complexes: solid thin films comprised of the components, and samples of solid neon or argon seeded with small quantities of them. These measurements will be combined with theoretical calculations to determine gas-phase structural and energetic properties, which provide insight into the extent of the structural changes, as well as the mechanism by which condensed-phase environments manifest them. Beyond fundamental motivations, this work may ultimately lead to a new class of molecular machines or switches, because the complexes sought contain individual bonds that can be affected by a macroscopic, external stimulus. This is the key design feature of all systems that underlie nanotechnology applications. Moreover, this research will take place at a low-cost, accessible, public university with a track record of advancing the careers of low-income and first-generation students, of which a high percentage matriculate to PhD programs. As such, continued funding for this project will enhance opportunities for these students to gain experience with specialized instruments and computational methods that would not occur in a classroom setting, and also bolster their writing and presentation skills.

化学系的化学结构，动力学和机制计划支持威斯康星大学 - 欧克莱尔大学（UWEC）的詹姆斯·A·菲利普斯教授和本科研究专业的研究。菲利普斯（Phillips）和他的学生将扩展他们以前的实验和理论研究，对一类新的刘易斯酸碱复合物，该研究经历了各种化学环境之间的显着结构变化（即，当它们从气相转移到溶液时）。它们的主要实验技术是低温红外光谱法，该光谱法应用于这些复合物的两种样品环境：由组件组成的实心薄膜，以及固体霓虹灯或氩气的样品，含量少量。这些测量结果将与理论计算结合使用，以确定气相结构和能量性能，从而洞悉结构变化的程度，以及凝结相环境表现出它们的机制。除了基本动机之外，这项工作最终可能导致新的分子机器或开关，因为所寻求的综合体包含可能受宏观外部刺激影响的个体键。这是纳米技术应用程序基础的所有系统的关键设计功能。此外，这项研究将在一所低成本，可访问的公立大学中进行，其记录记录，以推进低收入和第一代学生的职业，其中很高的博士学位课程。因此，该项目的持续资金将为这些学生提供获得专业仪器和计算方法的经验，这些机会不会在课堂环境中发生，并增强他们的写作和演讲技巧。
