9408561 Hoffman Northwestern University Dr. Brian M. Hoffman, Chemistry Department, Northwestern University, is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program of the Chemistry Division for a collaborative project with Dr. Anthony G. M. Barrett, Chemistry Department, Imperial College of Science and Technology, London, England, for the synthesis and study of star porphyrazines, solitaire phthalocyanines and related multimetallic macrocycles. A series of porphyrazines bearing a variety of ligating ring subsituents will be synthesized. These will be converted into multimetallic arrays, with metals bound to the peripheral heteroatoms as well as to the core of the central macrocycle. The resultant complexes may exhibit unusual spectroscopic, magnetic, or electrical properties properties due to electron delocalization and metal-metal interactions via the macrocycle pi-system. Compounds in which contain several metals often have unique magnetic and electronic properties. In this project a series of such materials will be prepared. The specific design involves a central metal which is surrounded by a rigid structure of other atoms (a macrocyclic ligand) to which additional metal are attached. This results in star shaped or linear arrays of metal atoms which are expected to have a diversity of applications in such areas as materials research, catalysis, and diagnostic and therapeutic medicine.

9408561西北大学化学系布莱恩·M·霍夫曼博士与英国伦敦帝国理工学院化学系安东尼·G·M·巴雷特博士合作开展了一个项目，旨在合成和研究星形卟嗪、纸板酞菁和相关的多金属大环。将合成一系列含有各种连接环替代物的卟嗪化合物。这些将被转换成多金属阵列，金属结合到外围杂原子以及中心大循环的核心。由于电子离域和通过大环pi体系的金属-金属相互作用，所生成的络合物可能表现出不寻常的光谱、磁性或电学性质。含有多种金属的化合物通常具有独特的磁学和电学性质。在这个项目中，将准备一系列这样的材料。具体的设计包括中心金属被其他原子(大环配体)的刚性结构所包围，附加的金属被附着在该结构上。这导致了金属原子的星形或线形阵列，有望在材料研究、催化以及诊断和治疗医学等领域有不同的应用。
