This CAREER award by the Inorganic, Bioinorganic and Organometallic Chemistry program supports work by Professor Darren Johnson at the University of Oregon to develop a program that links fundamental research in main group supramolecular coordination chemistry to internship opportunities for graduate students in environmental chemistry at regional companies and national laboratories. The research focuses on developing a predictive design strategy for forming self-assembled nanoscale main group supramolecular complexes. By using the unusual coordination geometries of As3+ and Pb2+ to develop a design strategy for forming supramolecular complexes, new supramolecular structure types result, providing three-dimensional molecules that are capable of exhibiting unusual host-guest chemistry. Programming the coordination preferences of these toxic metals into the design strategy will provide new ligands that are not only specific for the targeted metal ions, but also form extremely stable complexes. Students working on this project will have the opportunity to apply what they learn about ligand design to developing materials for remediation and sensing by performing off-campus internships at regional companies and national laboratories. Other educational activities include adding a Peer-Led Team Learning component to the undergraduate organic curriculum at the University of Oregon (UO), adding an immersion lab in polymer synthesis and characterization to improve the problem-solving and team-working skills in our masters-level polymer program, and providing support for the new Women in Graduate Sciences group to run a workshop and seminar series to create new networking and career-development opportunities for the group's members. The research aims to advance the basic science of arsenic and lead coordination chemistry, which will lead to long-term applications in the area of environmental and in vivo toxic metal remediation, sensing and ligand design. The educational activities will 1) provide internship opportunities for students to investigate more applied aspects of their research at regional industry or a national laboratory, 2) add new curricula to undergraduate organic chemistry and masters-level polymer chemistry courses at UO to improve problem-solving and team-working skills, and 3) provide support for a seminar and workshop series for members of the new Women in Graduate Sciences group at UO.

该职业奖由无机、生物无机和有机金属化学项目颁发，支持俄勒冈大学达伦·约翰逊教授的工作，开发一个项目，将主族超分子配位化学的基础研究与地区公司和国家实验室环境化学研究生的实习机会联系起来。 该研究的重点是开发形成自组装纳米级主族超分子复合物的预测设计策略。 通过使用 As3+ 和 Pb2+ 的不寻常的配位几何形状来开发形成超分子复合物的设计策略，产生新的超分子结构类型，提供能够表现出不寻常的主客体化学的三维分子。 将这些有毒金属的配位偏好编程到设计策略中将提供新的配体，这些配体不仅对目标金属离子具有特异性，而且还能形成极其稳定的络合物。从事该项目的学生将有机会通过在地区公司和国家实验室进行校外实习，将他们所学到的配体设计知识应用于开发修复和传感材料。 其他教育活动包括在俄勒冈大学 (UO) 的本科生有机课程中添加同伴主导的团队学习部分，添加聚合物合成和表征浸入式实验室，以提高硕士水平聚合物项目中解决问题和团队合作的技能，并为新的研究生科学女性小组提供支持，举办研讨会和系列研讨会，以创建新的网络和 为团体成员提供职业发展机会。 该研究旨在推进砷和铅配位化学的基础科学，这将导致在环境和体内有毒金属修复、传感和配体设计领域的长期应用。 这些教育活动将：1）为学生提供实习机会，让他们在地区工业或国家实验室研究更多的应用方面的研究；2）为俄勒冈大学本科生有机化学和硕士水平的聚合物化学课程添加新课程，以提高解决问题和团队合作的技能；3）为俄勒冈大学新女性研究生科学研究小组成员的研讨会和讲习班系列提供支持。
