Carbon Oxide Dual Square Lattices
We demonstrated a molecular-orbital engineering strategy to construct an edge-centered dual square lattice in a π-conjugated 2D-tetraoxa[8]circulene covalent organic framework (COF). First-principles calculations and scanning tunneling spectroscopy reveal an exotic band crossing at the Fermi energy. This approach establishes a general design principle for tailoring electronic structures in conjugated COFs, opening pathways to explore emergent topological phases in synthetic 2D materials for next-generation information technologies.

We introduced a modular strategy to construct one-dimensional chains and two-dimensional Kagome lattices from NHC–Au–NHC junctions. The interaction between NHC carbene frontier molecular orbitals and Au atoms in these metal organic frameworks gave rise to intrinsic metallicity. Scanning tunneling spectroscopy and density functional theory show that the unusual π-bonding states generate dispersive bands with work functions comparable to those of alkali metals. Explore more →
Quantum confinement and electron–electron interactions in graphene nanoribbons (GNRs) typically gives rise to sizable band gaps, precluding the realization of robust metallic states. Intrinsically metallic GNRs can be achieved by embedding a symmetric superlattice of zero-energy modes. The emergence of a dispersive metallic band is confirmed by scanning tunneling spectroscopy and theory. The bandwidth can be tuned over a wide range by controlling the overlap of zero-mode wave functions through molecular design and sublattice symmetry breaking. Explore more →
