Abstract

We present an implementation of strategies to deposit single-molecule magnets (SMMs) using microcontact printing microCP). We describe different approaches of microCP to print stripes of a sulfur-functionalized dodecamanganese (III, IV) cluster on gold surfaces. Comparison by atomic force microscopy profile analysis of the patterned structures confirms the formation of a chemically stable single layer of SMMs. Images based on chemical contrast, obtained by time-of-flight secondary ion mass spectrometry, confirm the patterned structure.

摘要

我们展示了一种使用微接触印刷（μCP）来沉积单分子磁体（SMMs）的策略的实施方案。我们描述了通过微接触印刷在金表面上印刷硫功能化十二锰（III，IV）簇条纹的不同方法。通过对图案化结构的原子力显微镜轮廓分析进行比较，证实形成了化学稳定的单分子磁体单层。通过飞行时间二次离子质谱获得的基于化学对比度的图像证实了图案化结构。
