Tuning Morphology and Fluorescence of Aggregated Nanostructures of Derived Perylene Diimide Molecules
In this paper, we report on the self-assembly of water-soluble N,N′-di(N,N′-dimethyl-dodecane-1,12-diamide)-perylene-3,4,9,10-tetracarboxylic diimide (PDDoAM) in formic acid and chloride salts for producing varied nano-aggregates with different
optical properties. Interestingly, the self-assembly can lead to nanocubic, microsheet and “tower-like” nanostructures respectively, as demonstrated by Scanning Electron Microscopy (SEM) images. The optical properties of molecular aggregates were investigated by means of Confocal
Raman Microscopy, indicating the morphologies and fluorescence of these nanomaterials are dependent on acids, acid concentrations and casting methods.
