Molecular Materials from Complexes with Bipyridine-like Ligands: Novel Electrides

本研究项目旨在合成一系列有机金属配合物，包括钌II、铁II或锇II与联吡啶类配体配合，具有不同寻常的几何形状和结构。这些化合物将使用电化学和电子自旋共振（ESR）相结合的方法来表征，以确定诸如电结晶和金属中心之间、配体结构之间的电子耦合程度，以及分子内电荷和自旋离域等性质。新的固态材料将通过电结晶技术从这些化合物中制备出来，以产生足够质量的单晶材料，以便使用诸如x射线衍射，光谱学，功率和导热系数（温度和磁场的函数）等技术进行分析。目的是获得一类独特的新型分子材料，具有不寻常的和可能在技术上有用的传输特性。这类有趣的化合物作为一种非常不寻常和非常有趣的材料的来源正在被探索，这些材料具有新颖的电子、磁性和光学特性。这些研究可能导致将电子用作器件的固态电子或磁性材料

9803088EchegoyenThis research program aims to synthesize a series of organometallic complexes consisting of ruthenium II, iron II, or osmium II coordinated to bipyridine-like ligands that exhibit unusual geometries and architectures. The compounds will be characterized using a combination of electrochemistry and electron spin resonance (ESR) to determine properties such as electrocrystallization and the degree of electronic coupling between metallic centers, between theligand structures, as well as intramolecular charge and spin delocalization. Novel solid-state materials will then be prepared from these compounds by electrocrystallization techniques to generate sisngle crystalline materials of sufficient quality to be analyzed using techniques such as x-ray diffraction, optical spectroscopy, power, and thermal conductivity as a function of temperature and magnetic field. The aim is to obtain a unique class of novel molecular materials with unusual and possibly technologically useful transport properties.%%%This interesting class of compounds is being explored as a source of highly unusual and very interesting materials exhibiting novel electronic, magnetic and optical properties. These investigations may lead to the use of electrides as solid-state electronic or magnetic materials for devices.***
