摘要

我们探究了自由电子作用下配体与丙烯酸四羰基甲基铁(Fe(CO)4(C4H6O2) 或 Fe(CO)4MA)的分离。研究的动机来自于将这种分子用作纳米制造前体的可能性,以及了解电子诱导沉积的基本反应的相应需求。我们利用了两种互补的电子碰撞设置,并通过量子化学计算来支持对数据的解释。这样,解离电离和解离电子附着碎片通道都得到了表征。在这两种途径中观察到的前驱体破碎程度存在很大差异。将这种前体与结构相似的五羰基铁进行比较,也会发现有趣的差异。本研究结果揭示了在超高真空条件下,Fe(CO)4MA 表面最近的电子诱导化学反应。

Electron-induced ligand loss from iron tetracarbonyl methyl acrylate.

We probe the separation of ligands from iron tetracarbonyl methyl acrylate (Fe(CO)4(C4H6O2) or Fe(CO)4MA) induced by the interaction with free electrons. The motivation comes from the possible use of this molecule as a nanofabrication precursor and from the corresponding need to understand its elementary reactions fundamental to the electron-induced deposition. We utilize two complementary electron collision setups and support the interpretation of data by quantum chemical calculations. This way, both the dissociative ionization and dissociative electron attachment fragmentation channels are characterized. Considerable differences in the degree of precursor fragmentation in these two channels are observed. Interesting differences also appear when this precursor is compared to structurally similar iron pentacarbonyl. The present findings shed light on the recent electron-induced chemistry of Fe(CO)4MA on a surface under ultrahigh vacuum.
