Abstract

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