Wiring on an atomic scale is one of the main goals of modern nanoelectronics. In this context, we studied one-dimensional coordination polymers on insulating surfaces using frequency-modulation atomic force microscopy (FM-AFM). We have deposited a Zn(II) coordination polymer onto mica and silicon oxide surfaces and have observed a significant effect of the surface on the organization of the polymer. On silicon oxide surfaces, linear single polymer strands as well as double helical structures were observed. On mica, however, 2-dimensional networks of intersecting polymer strands were formed. In addition, we have characterized Cu(II) coordination polymers on mica surfaces. However, we could not map a single polymer strands. Instead, we were able to acquire high resolution images of various, more complex patterns. In conclusion, FM-AFM proved to be an effective technique for investigating and classifying potential nanowires under ambient conditions.
