Self-Assembly, Aggregation Mechanisms, and Morphological Properties of Asymmetric Perylene Diimide-based Supramolecular Polymers.

ABSTRACT: The ability to control the self-assembly behavior of functional molecules offers pathways for optimizing their properties and structures for targeted applications. Asymmetric perylene diimide (PDI) derivatives, bearing similar oligo(ethylene glycol) (OEG) chains and increasing numbers of hydrophobic alkyl chains were used to investigate the effects of hydrophilic and hydrophobic groups on the properties of the resulting supramolecular polymers (SMPs). Tetrahydrofuran/water (THF/H₂O) mixtures were found to be an optimal system to induce the self-assembly behavior of these asymmetric PDI derivatives; the behavior of these new systems was monitored by recording ultraviolet-visible (UV/Vis) spectra and analyzing changes in absorbance intensity.
