项目摘要

In this project, funded by the Chemical Structure, Dynamics, and Mechanisms B Program of the Chemistry Division, Professors Jeanne E. Pemberton and Steve D. Schwartz of the Department of Chemistry and Biochemistry at the University of Arizona are developing a new class of conductive liquids to be used in batteries. These new materials, glyonic liquids, are made from biomass (e.g., sugars) and are biodegradable and nontoxic. The goal of this research is to optimize the conductive properties of these materials by molecular design and tp explore their applications as green, renewable conductive electrolytes in devices used for sensing and energy conversion and storage. The project lies at the interface of organic, physical and materials chemistry. This effort will also support the development of new intellectual property and educational initiatives at the graduate, undergraduate and K-12 science levels, with a particular emphasis on impacting members of underrepresented groups who are a large demographic base in southern Arizona. Outreach activities include the development of a workshop for in-service secondary science teachers on green chemistry and sustainability.Glyonic liquids are a new type of protic ionic liquid structurally based on a rhamnolipid platform as the anion can be paired with a variety of cations. These materials have demonstrated intriguing conductive properties that might make them excellent choices for use in electrochemical devices. Toward that end, this effort involves three specific objectives: 1) synthesis and property tuning of glyonic liquids based on the rhamnolipid structural motif through exploitation of synthetic handles that facilitate retention of these materials in the liquid state at or near room temperature; 2) exploration of electrochemical applications of these glyonic liquids; and 3) computational studies on glyonic liquids to define inter/intramolecular interactions and structure at the nano- and meso-scales as a function of temperature.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在这个由化学部门化学结构、动力学和机制B项目资助的项目中，亚利桑那大学化学和生物化学系的Jeanne E. Pemberton教授和Steve D. Schwartz教授正在开发一种用于电池的新型导电液体。这些新材料，糖醛酸液体，由生物质（如糖）制成，可生物降解且无毒。本研究的目标是通过分子设计优化这些材料的导电性能，并探索它们作为绿色、可再生导电电解质在传感、能量转换和存储设备中的应用。本项目处于有机化学、物理化学和材料化学的交叉点。这项工作还将支持研究生、本科生和K-12科学水平的新知识产权和教育举措的发展，特别强调对亚利桑那州南部人口基数较大的代表性不足群体的影响。外展活动包括为在职中学科学教师举办关于绿色化学和可持续性的讲习班。糖醛酸液体是一种基于鼠李糖脂平台的新型质子离子液体，阴离子可与多种阳离子配对。这些材料已经显示出有趣的导电性能，这可能使它们成为电化学器件的绝佳选择。为此，本研究涉及三个具体目标：1)基于鼠李糖脂结构基序的糖醛酸液体的合成和性质调整，通过开发有助于这些材料在室温或接近室温下保持液态的合成手柄；2)糖醛酸液体的电化学应用探索；3)糖醛酸液体的计算研究，以确定分子间/分子内的相互作用和结构在纳米和中观尺度上作为温度的函数。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
