Area of Science:

  • Supramolecular Chemistry
  • Materials Science

Background:

  • Subphthalocyanine-based capsules are dynamic supramolecular assemblies.
  • Understanding their stability and reorganization is crucial for applications.

Purpose of the Study:

  • To investigate the structural reorganization of kinetic mixtures of self-assembled subphthalocyanine capsules.
  • To determine the pathway towards more stable supramolecular structures.

Main Methods:

  • Utilized electrospray mass spectrometry (ESI-MS) to analyze the kinetic mixture.
  • Monitored changes in capsule composition and structure over time.

Main Results:

  • Observed a gradual reorganization of the initially formed capsules.
  • Demonstrated the transformation into thermodynamically more stable, symmetrical components.
