In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program in the Division of Chemistry, Professor Sergiy Rosokha of the Department of Chemistry at Ball State University studies intermolecular interactions between molecules that have a halogen atom (fluorine, chlorine, bromine, iodine) and molecules with a negative charge (anions). These types of chemical interactions are recognized as a powerful tool for recognizing molecules, preparing materials, and designing pharmaceuticals. Professor Rosokha is studying the role of these novel types of intermolecular interactions in facilitating certain chemical reactions. These mechanistic studies should aid the development of more efficient synthetic methods and the study of chemical reactions in the environment. Professor Rosokha is also providing research and training opportunities for undergraduate and masters students at Ball State University. Professor Rosokha is studying the mechanistic role of anion-pi and halogen-bonded complexes in electron-transfer reactions. More generally, he is addressing solution-phase chemical transformations of both halogenated electrophiles and anionic nucleophiles. Through a combination of spectral (UV-Vis, FT-IR, NMR, ESR) measurements, electrochemical, X-ray structural studies, and computational analysis, Professor Rosokha is establishing the structural, thermodynamic and spectral characteristics of highly-reactive pre-equilibrium halogen-bonded and anion-pi complexes. The properties of these complexes are then being used to explain, predict and, ultimately, control kinetics and stereochemistry of the reactions of halogen-containing molecules with anions.

在这个由化学系高分子、超分子和纳米化学项目资助的项目中，鲍尔州立大学化学系的 Sergiy Rosokha 教授研究了具有卤素原子（氟、氯、溴、碘）和带负电荷的分子（阴离子）。 这些类型的化学相互作用被认为是识别分子、制备材料和设计药物的强大工具。 Rosokha 教授正在研究这些新型分子间相互作用在促进某些化学反应中的作用。 这些机理研究应有助于开发更有效的合成方法和环境中化学反应的研究。 Rosokha 教授还为鲍尔州立大学的本科生和硕士生提供研究和培训机会。 Rosokha 教授正在研究阴离子-pi 和卤素键配合物在电子转移反应中的机械作用。更一般地说，他正在研究卤代亲电子试剂和阴离子亲核试剂的溶液相化学转化。 通过结合光谱（UV-Vis、FT-IR、NMR、ESR）测量、电化学、X 射线结构研究和计算分析，Rosokha 教授正在建立高反应性预平衡的结构、热力学和光谱特征卤素键合和阴离子π配合物。 这些配合物的性质随后被用来解释、预测并最终控制含卤素分子与阴离子反应的动力学和立体化学。
