Nanoscale Engineering of Molecular Porphyrin Wires on Insulating Surfaces

Ordered nanostructures of meso‐(4‐cyanophenyl)‐substituted Zn(II) porphyrin molecules are formed along step edges and specific directions of KBr(001). Short and long molecular wires, ringlike structures, and oriented multiwires (see image) are observed by high‐resolution noncontact atomic force micr...

Description
Summary:Ordered nanostructures of meso‐(4‐cyanophenyl)‐substituted Zn(II) porphyrin molecules are formed along step edges and specific directions of KBr(001). Short and long molecular wires, ringlike structures, and oriented multiwires (see image) are observed by high‐resolution noncontact atomic force microscopy on insulating surfaces. Intermolecular distances of 0.5–0.6 nm indicate π–π stacking of the porphyrin rings, which is comparable to natural light‐harvesting structures.
