Robust formation of discrete non-covalent pyrene dimers in an amorphous film by strong π-π interaction

A pyrene-based non-covalent dimer in a crystal showed a strengthened pi-pi interaction, which was robust enough against external disturbances. Such a strong pi-pi interaction made the pyrene-based dimer easily form in the amorphous film, indicating that the dimer could potentially work as the monomer.

Automated summary

A pyrene-based non-covalent dimer was found to exhibit a strengthened pi-pi interaction in both crystal and amorphous film, indicating its stability and potential as a monomer.
