In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Kim Dunbar of the Texas A&M University will seek to understand the structural and composition parameters that lead to the coexistence of molecular magnetism and conductivity in the same extended framework material. The approach is to create binary extended solids of transition metal and lanthanide cations or complexes with radical anions of tetracyanoquinodimethane (TCNQ) and its perfluoro(TCNQF4), TCNQCl2 and TCNQBr2 analogs. The structures of the resulting compounds will be determined and correlated with their magnetic and conductive properties. The broader impacts involve multidisciplinary training of students, exposure of the students to international collaboration, judging local science fair competitions, setting up hands-on exhibits at the Brazos Valley Children's Museum, and launching the magnetism website from the prior review period.This work will expand the repertoire of chemistry that can be used to create magnetic and conducting materials starting with molecular components. The results of these studies could have many important long term impacts on a variety of applications in which magnetic materials are important, including non-volatile memory and spintronics.

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，德克萨斯农工大学的 Kim Dunbar 将寻求了解导致分子磁性和导电性在同一扩展框架材料中共存的结构和组成参数。 该方法是用四氰基醌二甲烷 (TCNQ) 及其全氟 (TCNQF4)、TCNQCl2 和 TCNQBr2 类似物的自由基阴离子创建过渡金属和镧系阳离子或络合物的二元扩展固体。 所得化合物的结构将被确定并与其磁性和导电特性相关联。 更广泛的影响包括对学生进行多学科培训、让学生接触国际合作、评判当地科学博览会竞赛、在布拉索斯谷儿童博物馆设立动手展览，以及在上一个审查期间推出磁力网站。这项工作将扩展可用于从分子成分开始制造磁性和导电材料的化学体系。 这些研究的结果可能会对磁性材料发挥重要作用的各种应用产生许多重要的长期影响，包括非易失性存储器和自旋电子学。
