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.

在这个项目中，由化学部的化学结构，动力学和机制B计划资助，珍妮·E·彭伯顿教授和亚利桑那大学化学和生物化学系的珍妮·E·彭伯顿（Jeanne E. Pemberton）和史蒂夫·D·施瓦茨（Steve D. 这些新材料，乙二醇液体，由生物质（例如糖）制成，可生物降解且无毒。这项研究的目的是通过分子设计优化这些材料的导电性能，TP探讨了它们的应用，作为用于感应，能量转换和存储的设备中的绿色，可再生导电电解质。该项目位于有机，物理和材料化学的界面。这项努力还将支持研究生，本科和K-12科学水平的新知识产权和教育计划的发展，并特别着重于影响代表性不足的群体的成员，这些群体是亚利桑那州南部的大型人口基础。外展活动包括开发用于绿色化学和可持续性的服务中学科学教师的研讨会。基准液体是一种基于鼠李胺脂质平台的新型普利亚离子液体，因为阴离子可以与各种阳离子配对。这些材料显示出有趣的导电性能，可能使它们成为电化学设备中使用的绝佳选择。为此，这项工作涉及三个特定的目标：1）基于鼠李糖液结构基序的糖液合成和特性调整，通过开发合成手柄，从而促进这些材料在室温下或接近室温下将这些材料保留在液态下； 2）探索这些差异液体的电化学应用； 3）关于甘氨酸液体的计算研究，以定义纳米和中间尺度上的分子间相互作用和结构，这是温度的函数。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准来通过评估来通过评估来支持的。
