Area of Science:

• Supramolecular Chemistry
• Surface Science
• Chirality Studies

Background:

• Chiral induction and amplification are crucial in creating specific molecular arrangements.
• Surface-confined supramolecular assemblies offer unique platforms for studying chiral phenomena.
• Previous methods for chiral induction were primarily applied to solutions and polymers.

Purpose of the Study:

• To investigate chiral induction and amplification in surface-confined supramolecular monolayers.
• To demonstrate the formation of globally chiral patterns from achiral molecules at the liquid-solid interface.
• To adapt and validate methods for chiral induction and amplification at interfaces.

Main Methods:

• Utilizing scanning tunneling microscopy (STM) to visualize molecular self-assembly.
• Employing chiral solvents for direct chiral induction.
• Developing and applying a novel chiral amplification method.
• Investigating self-assembly at the liquid-solid interface.

Main Results:

• Achiral molecules successfully self-assembled into globally chiral patterns.
• Both chiral solvent induction and the novel chiral amplification method were effective.
• Demonstrated the feasibility of creating chiral supramolecular monolayers at the liquid-solid interface.
• STM confirmed the formation of well-defined chiral structures.

Conclusions:

• Chiral induction and amplification are viable strategies for creating chiral supramolecular monolayers at liquid-solid interfaces.
• The study validates the transferability of solution-based chiral techniques to surface-confined systems.
• This work opens avenues for designing and controlling chirality in interfacial molecular assemblies.
