New Highly Conducting Molecular Crystals

该计划致力于基于金属有机（M(L)）配合物的新型导电和磁性材料的合成和表征。本提案第一部分描述了由金属卟啉和酞菁制备的准一维分子金属的研究。这些材料显示出其他种类材料无法比拟的非凡特性，特别是一种新型的M(L)堆栈内的低温冷凝，它展示了嵌入导电有机框架的“费米海”中的金属离子局部矩的一维脊。第二节描述了可以进行高度三维相互作用的平面表面环金属巨环的合成。这些化合物还将用于制备多金属卟啉配合物和定义明确的二维金属连接聚合物，这些聚合物将作为薄膜和纤维进行研究。第三节介绍了过渡金属离子的三-二硫族配合物的新材料的制备。这些配合物为分子金属、超导体和铁磁体的合成提供了固有的三维构建块。

The program is devoted to the synthesis and characterization of novel conductive and magnetic materials based on metal-organic (M(L)) complexes. Section I of this proposal describes the study of quasi one-dimensional molecular metals that are propared from metalloporphyrins and phthalocyanines. These show remarkable properties without parallel in other classes of material, in particular a new type of low-temperature condensation within an M(L) stack that exhibits a one-dimensional spine of metal-ion local moments embedded within the "Fermi Sea" of a conducting organic framework. Section II describes the synthesis of planar surfur-encircled metallomacrocycles that can engage in highly three-dimensional interactions. These compounds will also be used to prepare multi-metal porphyrin complexes and well-defined, two-dimensional metal-linked polymers that will be studied as films and fibers. Section III describes the preparation of new materials based on tris-dichalcogenide complexes of transition-metal ions. These complexes provide inherently three-dimensional building blocks for the synthesis of molecular metals, superconductors and ferromagnets.
