    Direct Observation
    of the Zigzag Edge States of a
    Supramolecular Diatomic Kagome Lattice

## Description

- description: Lattice geometry plays a fundamental role in the behavior of Bloch
    electrons in a crystal. The diatomic Kagome lattice, an extension of the honeycomb
    and Kagome lattices, is predicted to give rise to emergent and topological phenomena,
    but its experimental investigation has been limited thus far. Here, we fabricate
    a diatomic Kagome lattice through self-assembly of a triptycene derivative with
    phenazine moieties (Trip-Phz)—a C3 -symmetric, non-planar π-conjugated molecule.
    Our scanning tunneling microscopy (STM) observations show that Trip-Phz forms
    a highly ordered diatomic Kagome lattice terminated by zigzag-type edges on the
    Pb(111) surface. Combined STM measurements and tight-binding calculations provide
    direct evidence for the existence of the edge states that correspond to those
    of graphene. These states are topological edge states dictated by the quantization
    of the Zak phase and the bulk-edge correspondence. This work reveals an ideal
    platform for exploring quantum materials with unique lattice geometries using
    supramolecular technology.
