Supramolecular organization and electronic structure of perylene tetracarboxylic diimide: X-ray diffraction and theoretical studies

摘要

The inter- and intracolumnar arrangements of the perylene tetracarboxylic diimide (PDI) was investigated experimentally and theoretically by using X-ray diffraction with combined DFT computation and molecular dynamics simulation. The structure was found to be hexagonal with a packing parameter of nearest column a = 2.025 nm characterized by a ~ 45° twist of molecules within the columns.
