Theoretical study of fluorescence of self-assembling helical supramolecular aggregates

The helical self-assembly of MOPV4 oligomers dissolved in dodecane solution has a large effect on the experimental fluorescence spectra. To describe the change in fluorescence upon aggregation, we combine a statistical mechanical theory describing the helical self-assembly with a tight-binding model to account for the delocalization of the exciton. We find our combined model to describe the red-shift of the main fluorescence peak upon aggregation qualitatively.
