Very small molecules common in interstellar space are often unstable and very reactive. For example, the compound that contains a phosphorus atom (P) bonded to a single nitrogen atom (N) was the first phosphorus compound to be detected in space, but this molecule has only fleeting existence on earth because it easily reacts with other molecules. Nonetheless, this P-N species has been proposed as a starting materials for electronic and magnetic materials. Because these molecules are so simple, but so reactive, a very important research topic is focused on how to prepare and stabilize them. In this project, funded by the Chemical Synthesis Program of the Chemistry Division, Professor Jeremy Smith of the Department of Chemistry at Indiana University, is developing a new strategy to make a variety of simple, yet highly reactive molecules. The strategy involves individually attaching two atoms (P and N) to two different metals. These species are then brought into contact and the P and N then to bind each other, while being stabilized by the metals. In addition to training students for entry into the technological workforce, the team develops materials to assist teachers and the general public in reading and interpreting scientific research. In this project a combination of synthetic, spectroscopic and computational methods are used to assemble and characterize diatomic molecules as ligands in transition metal complexes. The modular nature of the building block strategy allows a range of diatomic molecules to be accessed, with the resulting compounds displaying unusual magnetic and reactivity properties. In collaboration with the Indiana University College of Arts and Science Office of Science Outreach, publications resulting from the research are deconstructed to assist teachers and the general public to understand and interpret the concepts, assumptions, and methods of scientific papers.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

星际空间中常见的非常小的分子通常是不稳定的，反应性很强。例如，含有一个磷原子(P)与一个氮原子(N)结合的化合物是第一个在太空中被探测到的磷化合物，但这种分子在地球上的存在时间很短，因为它很容易与其他分子发生反应。尽管如此，该P-N物种已被提议作为电子和磁性材料的起始材料。由于这些分子非常简单，但反应性很强，因此如何制备和稳定它们是一个非常重要的研究课题。在这个由化学部门化学合成项目资助的项目中，印第安纳大学化学系的杰里米·史密斯教授正在开发一种新的策略来制造各种简单但高活性的分子。该策略包括将两个原子（P和N）分别附着在两种不同的金属上。然后这些物质接触，P和N相互结合，同时被金属稳定。除了培训学生进入技术队伍外，该团队还开发了一些材料，以帮助教师和公众阅读和解释科学研究。在这个项目中，结合了合成、光谱和计算方法来组装和表征作为过渡金属配合物配体的双原子分子。构建块策略的模块化特性允许访问一系列双原子分子，由此产生的化合物显示出不同寻常的磁性和反应性。在与印第安纳大学艺术与科学学院科学拓展办公室的合作下，研究产生的出版物被解构，以帮助教师和公众理解和解释科学论文的概念、假设和方法。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
