本文研究了十二锰（Ⅲ，Ⅳ）团簇与两种不同配体（乙酸根和苯甲酸根）在Au（111）表面上的单分子磁体。由于分子的非挥发性和脆弱性，我们已经使用超高真空电喷雾沉积产生一系列的表面覆盖从一小部分的单层到多层膜在这两种情况下。利用同步辐射电子能谱研究了分子在Au（111）表面的吸附及其对核中锰原子氧化态的影响。在这两种情况下，由于与表面的相互作用，观察到核的还原，尽管配体壳的大小和性质存在实质性差异，但程度基本相同。
Single molecule magnets based on the dodecamanganese (III, IV) cluster with two different types of ligand (acetate and benzoate) have been studied on the Au (111) surface. Due to the non-volatile and fragile nature of the molecules, we have used ultra-high vacuum electrospray deposition to produce a series of surface coverages from a fraction of a monolayer to multilayer films in both cases. Synchrotron radiation based electron spectroscopy has been used to study the adsorption of the molecules on the Au (111) surface and the effect that this has on the oxidation states of the manganese atoms in the core. In both cases, reduction of the core is observed due to the interaction with the surface, to essentially the same extent despite substantial differences in the size and nature of the ligand shell.
