New Conductive and Magnetic Materials

这个研究项目致力于基于金属有机配合物的新型导电和磁性材料的合成和表征，包括晶体和聚合物。它由三个部分组成。第一个项目涉及卟啉分子金属。基于金属酞菁和相关大环的准一维金属具有其他类分子金属所没有的性质。新材料将用于研究与lD - 3D交叉转变相关的电子定位的基本问题，以及在低温和高压下看到的新型M-I-M转变。第二个项目涉及磁性有序电荷转移盐。目的是探讨分子磁体中堆叠间铁磁交换的机理，并研究分子磁体中磁有序态的详细特征。第三个项目与功能化卟啉类的导体和磁铁有关。功能化卟啉合成的突破为制备新型晶体分子金属和由卟啉（四氮卟啉）基多金属配合物衍生的磁体以及新型高度可加工的金属连接带状聚合物提供了长期计划的基础。本研究项目致力于基于金属有机配合物的新型导电和磁性材料的合成和表征，包括晶体和聚合物。它由三个部分组成：1)卟啉分子金属的研究；2)磁有序电荷转移盐的检验；3)功能化卟啉类化合物导体和磁体的研究。这项研究的成功完成将最终导致新的导体和磁体的发展。

9523228 Hoffman This research program is devoted to the synthesis and characterization of novel conductive and magnetic materials, both crystalline and polymeric, that are based on metal- organic complexes. It is comprised of three components. The first project is concerned with Porphyritic Molecular Metals. Quasi one-dimensional metals based on metallophthalocyanines and related macrocycles show properties without parallel in other classes of molecular metals. The new materials will be used to study the fundamental question of electron localization associated with a lD - 3D crossover transition, and a novel M-I-M transition seen at low temperatures and high pressure. The second project deals with Magnetically Ordered Charge- Transfer Salts. The aim is to explore the mechanism for interstack ferromagnetic exchange and to examine the detailed character of the magnetically ordered state in molecular magnets. The third project is connected to Conductors and Magnets From Functionalized Porphyrazines. Breakthroughs in the synthesis of functionalized porphyrazines provide the foundation for a long-term program to prepare new classes of crystalline molecular metals and magnets derived from porphyrazine (tetraazaporphyrin)-based multi-metallic complexes, and new types of highly processable metal-linked ribbon polymers. %%% This research program is devoted to the synthesis and characterization of novel conductive and magnetic materials, both crystalline and polymeric, that are based on metal- organic complexes. It is comprised of three components: 1) studies of Porphyritic Molecular Metals; 2) examinations of Magnetically Ordered Charge-Transfer Salts; and 3) investigation of Conductors and Magnets From Functionalized Porphyrazines. The successful completion of this research will eventually result in the development of new conductors and magnets.
