The use of organometallic pi-complexes in the coordination-directed self-assembly of polymeric structures is a new area with many potential applications. Supramolecular metal-organometallic coordination networks (MOMNs), which are described herein, consist of metal ion or metal cluster nodes connected by bifunctional "organometalloligands" that serve as spacers. The organometalloligand utilized in this work is the stable anionic complex (eta(4)-benzoquinone)Mn(CO)(3)(-) (p-QMTC), which binds through both quinone oxygen atoms to generate MOMNs having both backbone and pendant metal sites. In many cases the MOMNs are obtained as neutral and thermally stable solids, with molecular structures that depend on the geometrical and electronic requirements of the metal nodes, the solvent, and the presence of organic spacers. Redox-active quinone-based organometallic pi-complexes permit the construction of an impressive range of coordination network architectures and hold much promise for the development of functional materials.
有机金属π配合物在聚合物结构的配位导向自组装中的应用是一个具有许多潜在应用的新领域。本文所述的超分子金属 - 有机金属配位网络（MOMNs）由通过作为间隔基的双功能“有机金属配体”连接的金属离子或金属簇节点组成。本工作中使用的有机金属配体是稳定的阴离子配合物（η(4)-苯醌）Mn(CO)₃⁻（p-QMTC），它通过两个醌氧原子结合，生成具有主链和侧链金属位点的MOMNs。在许多情况下，MOMNs是以中性且热稳定的固体形式获得的，其分子结构取决于金属节点的几何和电子要求、溶剂以及有机间隔基的存在。基于氧化还原活性醌的有机金属π配合物能够构建一系列令人印象深刻的配位网络结构，并在功能材料的开发方面具有很大的前景。
