Experimental study demonstrates the synthesis of crystalline two-dimensional covalent organic frameworks on graphite, indicating a mild route for tunable nanomaterial fabrication.

Key Points

Synthesize surface-confined, crystalline two-dimensional covalent organic frameworks with low defect densities and tunable pore dimensions using mild Schiff-base condensation chemistry.
Conducted on-surface co-condensation between aromatic aldehyde and aromatic diamine monomers on highly oriented pyrolytic graphite (HOPG).
Carried out reactions either at a solid/liquid interface at room temperature or under low vacuum with moderate heating.
Characterized film morphology, domain size, pore tunability, and layer stacking using scanning tunneling microscopy (STM) and atomic force microscopy (AFM).
Formed two-dimensional covalent organic frameworks with minimal defects, nearly complete surface coverage, and single-crystalline domain areas exceeding 1 μm².
Achieved pore size tunability between ~1.7 and 3.5 nm by varying diamine backbone length, while functionalization was verified through backbone methyl group substitution.
Identified localized bilayer formations via STM and AFM that adopted an eclipsed stacking configuration.
