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.

在该项目由化学部的大分子，超分子和纳米化学计划资助的项目中，得克萨斯州A＆M大学的Kim Dunbar将寻求理解导致同一扩展框架材料中分子磁性和电导率共存的结构和组成参数。 该方法是创建带有四酰基喹啉二甲烷（TCNQ）及其perfluoro（TCNQF4），TCNQCL2和TCNQBR2 Analogs的二元延伸固体或具有四乙酸喹啉甲甲烷（TCNQ）的二元扩展固体。 所得化合物的结构将被确定并与它们的磁性和导电性能相关。 更广泛的影响涉及对学生进行多学科培训，将学生接触国际合作，评判本地科学博览会竞赛，在Brazos Valley儿童博物馆举行动手展览，并在先前的审查期间启动磁性网站。这项工作将扩大化学曲目，可用于创建具有磁性和动作材料的化学作品。 这些研究的结果可能会对磁性材料很重要的多种应用产生许多重要的长期影响，包括非挥发记忆和旋转型。
