Area of Science:

  • Supramolecular Chemistry
  • Materials Science
  • Nanotechnology

Background:

  • Host-guest chemistry explores molecular recognition and self-assembly.
  • Macrocyclic compounds offer unique structural frameworks for host-guest interactions.
  • Controlling self-assembly at interfaces is crucial for nanomaterial fabrication.

Purpose of the Study:

  • To fabricate and characterize host networks using novel phenanthrene-butadiynylene macrocycles (PBMs).
  • To investigate the host-guest interactions between PBMs and coronene (COR) molecules.
  • To understand the influence of concentration on the self-assembly and structural polymorphism of PBM/COR systems.

Main Methods:

  • Fabrication of host networks at the liquid-solid interface.
  • Size, shape, and concentration-controlled experiments.
  • Scanning tunneling microscopy (STM) for structural analysis.
  • Density functional theory (DFT) calculations for mechanism elucidation.

Main Results:

  • Phenanthrene-butadiynylene macrocycle 1 (PBM1) formed linear networks; PBM2 formed nanoporous networks.
  • Coronene (COR) was entrapped in PBM2 cavities, inducing structural transformation with increasing COR concentration.
  • PBM1 networks remained unchanged upon COR introduction.
  • Solution concentration was identified as a key factor controlling molecular nanoarray formation.

Conclusions:

  • Novel PBMs can form distinct host network architectures.
  • PBM2 exhibits selective host-guest encapsulation of COR, leading to concentration-driven structural polymorphism.
  • STM and DFT collectively reveal the mechanism of concentration-controlled molecular nanoarray assembly.
