dc.description.abstract | Porphyrin nanotapes (Por NTs) are promising structures for their use as molecular wires thanks to a high degree of pi-conjugation, low HOMO-LUMO gaps, and exceptional conductance. Such structures have been prepared in solution, but their on-surface synthesis remains unreported. Here, meso-meso triply fused Por NTs have been prepared through a two-step synthesis on Au(111). The diradical character of the on-surface formed building block PorA(2), a phenalenyl pi-extended Zn(II)Por, facilitates intermolecular homocoupling and allows for the formation of laterally pi-extended tapes. The structural and electronic properties of individual Por NTs are addressed, both on Au(111) and on a thin insulating NaCl layer, by high-resolution scanning probe microscopy/spectroscopy complemented by DFT calculations. These Por NTs carry one unpaired electron at each end, which leads to magnetic end states. Our study provides a versatile route towards Por NTs and the atomic-scale characterization of such tapes. | es_ES |
