Spin Dynamics in Multi-metallic Ligand Radical Compounds

自旋电子器件的核心是纳米级的磁有序系统，用于操纵和控制电子自旋。最近，随着人们意识到自旋电子学的潜在用途扩展到许多领域，包括高频发射器和探测器、高密度数据存储和量子信息处理，活动掀起了热潮。成功的体系需要多个自旋中心之间的合作和可调的相互作用，而这可以通过连接顺磁性金属离子和有机自由基配体的工程化合物来协调。具有自由基配体的多金属配合物的定向合成是非常具有挑战性的，因为各个组分的物理化学性质是非常不同的。这个博士项目将开发一个前所未有的实验模型，在这个模型中，我们可以有选择地将两个或更多具有可访问自旋的模块单元组合在一起，并对分子环境的各个方面进行化学操作。

At the heart of spintronic devices are nanoscale, magnetically ordered systems which are used to manipulate and control electron spin. Recently there has been upsurge in activities as it was realised that the potential usefulness of spintronics extends to many areas including high frequency emitters and detectors, high density data storage and quantum information processing. Successful systems require cooperation and tunable interaction between multiple spin centres, and this is can be orchestrated by engineering compounds that link paramagnetic metal ions and organic radical ligands. The directed synthesis of multi-metallic complexes with radical ligands is very challenging because the physico-chemical properties of the individual components are very different. This PhD project will develop an unprecedented experimental model in which we can selectively combine two or more modular units with accessible spins and chemically manipulate all aspects of the molecular environment.
