摘要

我们首次展示了稳定、多态可切换的聚氧化金属盐（POMs）单层的形成，这种单层可在室温下通过电子触发进入带电状态，并在电流-电压曲线上增加电导。这些响应性二维单层以完全氧化的十二钒酸盐笼（POV12）为基础，配备了掺杂镝（III）的酞菁（Pc）大环，在高取向热解石墨（HOPG）上采用面朝上取向。这些层可以通过扫描隧道显微镜（STM）的尖端进行光刻处理，加工出直径为 30 至 150 nm2 的图案。

Multistate switching of scanning tunnelling microscopy machined polyoxovanadate–dysprosium–phthalocyanine nanopatterns on graphite†

We demonstrate the first formation of stable, multistate switchable monolayers of polyoxometalates (POMs), which can be electronically triggered to higher charged states with increased conductance in the current–voltage profile at room temperature. These responsive two-dimensional monolayers are based on a fully oxidised dodecavanadate cage (POV12) equipped with Dy(III)-doped phthalocyanine (Pc) macrocycles adopting the face-on orientation on highly oriented pyrolytic graphite (HOPG). The layers can be lithographically processed by the tip of a scanning tunnelling microscope (STM) to machine patterns with diameters ranging from 30 to 150 nm².

期刊介绍： Nanoscale Horizons stands out as a premier journal for publishing exceptionally high-quality and innovative nanoscience and nanotechnology. The emphasis lies on original research that introduces a new concept or a novel perspective (a conceptual advance), prioritizing this over reporting technological improvements. Nevertheless, outstanding articles showcasing truly groundbreaking developments, including record-breaking performance, may also find a place in the journal. Published work must be of substantial general interest to our broad and diverse readership across the nanoscience and nanotechnology community.
