RUI: Chemical Methods for Isolating Metal Clusters Inside Large Fullerene Cages (C82-C140)

在这个由化学部化学结构、动力学机制B计划资助的项目中，印第安纳州普渡大学韦恩堡（IPFW）化学系的史蒂文史蒂文森教授将研究更大、更高富勒烯笼（HMNF）中捕获的金属氮化物簇的制备。 这些独特的分子在能量方面具有重要的潜在应用（例如，光化学），医学（例如，药物、MRI造影剂）和光电子学。 然而，它们很难大量获得。 史蒂文森教授的目标是通过提高反应产率和简化产物分离程序来改进这些分子的制备。 他的产品分离程序也将大大减少废溶剂的产生量。 该项目促进将代表性不足的学生群体、高中生和早期本科生（例如，大一，大二）学生在研究。 还将努力吸引非化学专业的学生，因为他们很少有机会进行化学研究。 该项目有三个具体目标。 在第一个目标中，新的分子将在等离子体反应器中选择性地产生。 通过将氧化剂结合到等离子体区中，反应器的内部将具有化学苛刻的环境，以抑制污染物物种的形成。 第二个目标是用于高效非色谱纯化HMNF的集成SAFA（搅拌和过滤方法）-刘易斯酸方法。 在第三个目标，与四个博士合作活动-授予机构将负责评估所准备的高净值国家基金的性质。

In this project funded by the Chemical Structure, Dynamic & Mechanism B Program of the Chemistry Division, Professor Steven Stevenson of the Department of Chemistry at Indiana University-Purdue University Fort Wayne (IPFW) will study the preparation of metallic nitride clusters entrapped within larger, higher fullerene cages (HMNFs). These unique molecules have significant potential applications in energy (e.g., photovoltaics), medicine (e.g., pharmaceuticals, MRI contrast agents), and optoelectronics. However, they are difficult to obtain in large quantity. Professor Stevenson aims to improve the preparation of these molecules by improving the reaction yield and by simplifying the product isolation procedure. His product isolation procedure will also reduce significantly the amount of waste solvents generated. The project promotes the inclusion of underrepresented groups of students, high school students and early undergraduate (e.g., freshman, sophomore) students in research. Efforts will also be made to attract non-chemistry major students, as they have few opportunities for chemical research. This project has three specific objectives. In the 1st objective, new molecules will be selectively created inside a plasma reactor. The interior of the reactor will possess a chemically harsh environment by incorporating oxidizing agents into the plasma zone, in order to suppress the formation of contaminant species. The 2nd objective is the integrated SAFA (the Stir and Filter Approach)-Lewis acid approach for the efficient non-chromatographic purification of HMNFs. In the 3rd objective, collaborative activities with four Ph.D.-granting institutions will serve to evaluate the properties of HMNFs prepared.
