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.

在这个由化学系化学结构、动力学和机理B计划资助的项目中，Jeanne E. Pemberton和Steve D.亚利桑那大学化学和生物化学系的Schwartz博士正在开发一种用于电池的新型导电液体。这些新材料，即glyonic液体，是由生物质制成的（例如，糖）并且是可生物降解的和无毒的。本研究的目的是通过分子设计优化这些材料的导电性能，并探索其作为绿色可再生导电电解质在传感、能量转换和存储等器件中的应用。该项目位于有机，物理和材料化学的界面。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开发，特别强调影响代表性不足群体的成员，这些群体是亚利桑那州南部的一大人口基础。外联活动包括为在职中学理科教师举办一个关于绿色化学和可持续性的讲习班。由于阴离子可以与多种阳离子配对，糖酸液体是一种新型的结构上基于鼠李糖脂平台的质子离子液体。这些材料已经证明了有趣的导电性能，这可能使它们成为电化学设备中使用的绝佳选择。为此，这项努力涉及三个具体目标：1）通过开发促进这些材料在室温或接近室温下保持液态的合成柄，合成和调节基于鼠李糖脂结构基序的糖基液体的性质; 2）探索这些糖基液体的电化学应用;和3）对glyonic液体的计算研究，以确定分子间/分子内相互作用和纳米和介观结构。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值进行评估，更广泛的影响审查标准。
