Ionic liquids are molten salts which are liquids at moderate temperatures (less than 100 degrees Celsius). They are important modern solvents because they do not evaporate, which lowers environmental impact costs for many reactions (their use constitutes "green" chemistry), and they allow for easier product separations. Newer applications are in catalysis and as electrolytes in batteries, but more research is needed to assist development in these important areas. The keys to how these liquids function are the weak bonds that they make with molecules dissolved in them, such as carbocations (for petroleum refining) and carbon dioxide (for curbing greenhouse gas emissions). Our tools of investigation will be theoretical development (pencil-and-paper) and computations. We will focus on three particular lines of research.

离子液体是在中等温度（低于100摄氏度）下为液体的熔融盐。 它们是重要的现代溶剂，因为它们不会蒸发，这降低了许多反应的环境影响成本（它们的使用构成“绿色”化学），并且它们允许更容易的产物分离。 较新的应用是催化和电池中的电解质，但需要更多的研究来帮助这些重要领域的发展。 这些液体如何发挥作用的关键是它们与溶解在其中的分子形成的弱键，例如碳阳离子（用于石油精炼）和二氧化碳（用于抑制温室气体排放）。 我们的调查工具将是理论发展（纸和纸）和计算。 我们将集中在三个特定的研究领域。
