Area of Science:

• Surface chemistry
• Materials science
• Nanotechnology

Background:

• Surface organic nanostructures are crucial for molecular electronics, energy conversion, and storage.
• Traditional preparation relies on intrinsic molecular and substrate components for assembly.
• A paradigm shift introduces extrinsic components to mediate and control nanostructure formation.

Purpose of the Study:

• To review extrinsic modulators for surface organic nanostructure construction and modification.
• To discuss the roles and mechanisms of extrinsic components at the single-molecule level.
• To highlight the potential of extrinsic-component-mediated assembly for supramolecular engineering and nanomaterials development.

Main Methods:

• Review of literature on extrinsic modulators (small gas molecules, metals, and their combinations).
• Analysis of single-molecule level mechanisms governing assembly and reaction pathways.
• Discussion of tailored assembly and reaction strategies.

Main Results:

• Identified three categories of extrinsic modulators: small gas molecules, metals, and their combinations.
• Detailed the mechanisms by which these extrinsic components regulate nanostructure formation.
• Demonstrated the ability to precisely control physicochemical properties of surface organic nanostructures.

Conclusions:
