Exchange-coupled Homo- and Heteropolynuclear Complexes

根据我们最近的研究结果，该研究建议分为两个领域，即制备配位化学和对合理合成的配合物的磁化学研究：具有不同分子拓扑结构的具有不规则自旋态结构和自旋受挫的异多核配合物的研究，以及基于空气氧化形成自由基配体的金属-配体自由基配合物的研究。这两个领域构成了将被研究的系统的综合计划，目的是获得“高自旋”分子。所得配合物将通过不同的光谱-COPIC方法(紫外可见、电子顺磁共振以及最终的穆斯堡尔)、磁化率测量和X射线结晶学进行表征。电化学将提供更多关于一般涉及的氧化还原过程的电位的知识，特别是关于空气中容易形成自由基的可行性的知识。该项目预计将对整个化学科学产生广泛的影响，并将极大地扩大分子磁学的范围。

The research proposal, based on our recent results, is divided in two areas of preparative coordination chemistry in conjunction with magnetochemical investigations of the rationally synthesized complexes: investigations of heteropolynuclear complexes with different molecular topology exhibiting irregular spin-state structures and spin frustration, and of metal-ligand radical complexes based on the facile formation of radical ligands by aerial oxidation. Both areas constitute an integrated program for the systems to be studied and are aimed to obtain "high-spin" molecules. The resulting complexes will be characterized by different spectros-copic methods (Ultraviolet-Visible, Electron Paramagnetic Resonance and eventually Mössbauer), magnetic susceptibility measurements and by X-ray crystallography. Electrochemistry will provide more knowledge on the potentials of the redox processes involved in general and in particular about the viability of facile formation of radicals by air. The proposed project is expected to have wide impact on chemical science in general and will greatly increase the scope of molecular magnetism.
