This research program targets the study of unprecedented diastereo- and enantiospecific photodimerization reactions in bimolecular crystals. Families of homochiral, racemic, and quasiracemic cinnamoylsulfonamides will be developed, and their crystal packing tendencies and photochemical crystal reactions explored. These studies provide student participants with broad experience in organic synthesis, crystal engineering, materials design, X-ray crystallography, and issues in chirality, crystal cohesion, chemical reactivity and nanotechnology.With the support of this award from the Macromolecular, Supramolecular, and Nanochemistry Program, Professor Wheeler, of the Department of Chemistry at Eastern Illinois University, will fine-tune solid-state reactivity via molecular engineering of constituent building blocks. This research program promises to delineate the relationship between molecular structure and the reactivity of the bulk solid with results leading to transformative developments in the areas of solid-state reactions and materials research. Findings from this program will be especially useful in future work for rationally designed multi-component solid-state reactions, where managing the spatial orientation of reactive components is often by chance rather than a well-defined preconceived approach to molecular assembly. This project also targets a number of other developments regarding recruitment and training in the chemical sciences through enhancing the research relevance of laboratory courses, devising novel approaches for incorporating advanced structure determination techniques in the undergraduate curriculum, and fostering career paths of students in the chemical and related fields. This project will have an important impact on society because of the current technological need for next generation methods for fabricating functional materials (e.g., optical materials and therapeutic agents).

这项研究计划的目标是研究双分子晶体中史无前例的非对映和对映异构光二聚反应。将开发同手性、外消旋和准外消旋肉桂酰磺酰胺类化合物，并探索它们的晶体堆积趋势和光化学晶体反应。这些研究为学生参与者提供了在有机合成、晶体工程、材料设计、X射线结晶学以及手性、晶体内聚力、化学反应性和纳米技术方面的广泛经验。在大分子、超分子和纳米化学项目的支持下，东伊利诺伊大学化学系的惠勒教授将通过组成构件的分子工程来微调固态反应性。这项研究计划承诺描绘分子结构和块状固体反应性之间的关系，并取得导致固态反应和材料研究领域的变革性发展的结果。该项目的发现将在未来合理设计多组分固态反应的工作中特别有用，在这些反应中，管理反应组分的空间取向通常是偶然的，而不是一种明确定义的预先设想的分子组装方法。该项目还旨在通过加强实验室课程的研究相关性、设计新的方法将先进的结构确定技术纳入本科课程以及培养化学及相关领域的学生的职业道路，在化学科学领域的招聘和培训方面取得一些其他进展。该项目将对社会产生重要影响，因为目前对制造功能材料(如光学材料和治疗剂)的下一代方法的技术需求。
