In this RUI project, funded by the Chemical Structure, Dynamics and Mechanisms B Program of the Chemistry Division, Professor Arsalan Mirjafari and his students of the Department of Chemistry & Physics at the Florida Gulf Coast University are developing new type of organic materials called ionic liquids. Ionic liquids are liquid salts comprised entirely of ions. The search for new ionic liquids is driven in part by efforts to address unmet needs in medicine and energy. Salts of this kind can be utilized as alternatives for more conventional organic solvents in various applications, including electronic materials, new generation of rechargeable batteries, and gene delivery. The project is designed to advance the scientific enterprise in tandem with educating and training undergraduate students to become the next generation of chemists. The project brings together elements of chemical synthesis, computer modeling as well as advanced materials development and characterizations, providing undergraduate students with opportunities to experience faculty-mentored research. Since Florida Gulf Coast University has a large underrepresented minority population in Science, Technology, Engineering, and Math (STEM) fields, the project provides important opportunities to engage in the professional training of individuals from these communities. Outreach activities involving local middle and high schools is part of the funded project as well. Fundamental to the field of ionic liquids is the understanding that structure begets function. In this project, Professor Mirjafari seeks the development of functional ionic liquids that simultaneously have improved fluidity and amphiphilic character – a combination of attributes that, while frequently antithetical, is very desirable in many applications. Click reactions are utilized to incorporate a diverse array of functional groups into the thioamide-based heterocyclic cations structures. The research involves efforts to understand the relationships between the chemical structure and physicochemical properties and the development of ionic liquids for specific functions including aliphatic/aromatic separation, liquid crystals, fluoride-ion electrochemistry, and gene transfer. New strategies are being pursued to improve the chemical stability and toxicity profiles of ionic liquids.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 项目资助的 RUI 项目中，佛罗里达海湾海岸大学化学与物理系的 Arsalan Mirjafari 教授和他的学生正在开发一种称为离子液体的新型有机材料离子液体是完全由离子组成的液体盐，部分原因是为了解决医学和能源方面未满足的需求。这种盐可以用作替代品。该项目旨在推动科学事业的发展，同时教育和培训本科生成为下一代化学家。化学合成、计算机建模以及先进材料开发和表征，为本科生提供了体验教师指导研究的机会，因为佛罗里达海湾海岸大学在科学、技术、工程和数学 (STEM) 领域拥有大量少数群体。 ， 这项目为来自这些社区的个人提供了参与专业培训的重要机会，也是该资助项目的一部分。离子液体领域的基础是理解结构产生功能。在该项目中，Mirjafari 教授寻求开发同时具有改善的流动性和两亲特性的功能性离子液体，这两种特性虽然经常是对立的，但在许多应用中是非常理想的，可利用点击反应将各种官能团纳入其中。研究工作涉及了解化学结构和物理化学性质之间的关系，以及开发具有特定功能的离子液体，包括脂肪族/芳香族分离、液晶、氟离子电化学和基因转移。正在寻求新的策略来改善离子液体的化学稳定性和毒性特征。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优势和更广泛的影响进行评估，被认为值得支持审查标准。
