Professor Linda Shimizu of the University of South Carolina is supported by the Macromolecular, Supramolecular and Nanochemistry Program of the Division of Chemistry to develop bis-urea macrocycles that predictably assemble into columnar structures with homogeneous channels with diameters of ~ 1 nm or less. This proposal develops new self-assembling macrocycles, explores the use of these materials to absorb reactive molecules, and investigates the effects of carrying out reactions within this confined space.Fundamental understanding of the factors that govern the reaction of molecules in small spaces could lead to new methods for organic synthesis that utilize less reactive and safer reagents. Such synthetic improvements would be environmentally friendly and economical. This research provides training for undergraduates and graduate students in organic and materials chemistry. In addition, this award supports the continuation of a chemical demonstration program that brings chemists into South Carolina K-12 classrooms to showcase the scientific method and foster interest in chemistry and the natural sciences.

南卡罗来纳大学的Linda Shimizu教授得到了化学司的大分子，超分子和纳米化学计划的支持，以开发具有均匀途径的BIS-rea-rea宏大环节，这些型号可以预见到具有均匀的通道，其直径为〜1 nm或更少。 该提案开发了新的自组成巨环，探讨了这些材料吸收反应性分子的使用，并研究了在这个狭窄空间内进行反应的效果。对控制小空间中分子的反应的基本了解可能会导致有机合成的新方法，从而对有机的反应性和反应性更少。 这种合成的改进将是环保和经济的。 这项研究为有机和材料化学的本科生和研究生提供了培训。 此外，该奖项还支持一个化学演示计划的延续，该计划将化学家带入南卡罗来纳州K-12教室，以展示科学方法并促进对化学和自然科学的兴趣。
