Scientific Achievement
- Researchers in the Characterization of Functional Nanomachines program revealed that On-surface of 𝜋-conjugated covalent organic frameworks (COFs) enable the realization of designer quantum nanomaterials
Significance and Impact
- Demonstrates how molecular engineering of orbital-phase frustration within an aza-triangulene COF-based kagome lattice gives rise to non-trivial flat bands
Research Details
- Designed and performed on-surface synthesis of a class of 𝜋-conjugated diatomic Kagome COFs comprised of aza-triangulene cores
- Spectroscopically characterized the signatures of non-trivial flat bands emerging from orbital phase frustration
