Aromatic stacking and the self-assembly of perylene monoimide diester homodimers

Abstract

The self-assembly properties of two novel perylene monoimide diester homodimers have been investigated by concentration-dependent UV-Vis and H-1 NMR titration experiments and steady-state fluorescence and SEM techniques. It was found that, as a result of different positioning of the perylene monoimide diester subunits in these structures, the cooperativity and binding-models for their chain growth processes differ significantly in dichloromethane (DCM) and dimethyl sulfoxide (DMSO) due to a change in efficiency of the pi-pi stacking. The mechanism of aggregation in each case was determined by the application of Goldstein-Stryer nucleation - elongation model to the concentration-dependent data. Because of different aggregation propensities of the respective monomers in DCM, scanning electron microscopy revealed different morphologies for the assemblies.
