Abstract
Supramolecular self-assembly is showcased as a powerful tool for controlling exciton interactions and light polarization for organic optoelectronics. We will discuss a supramolecular pseudo-cube assembled from PDI chromophores with enhanced brightness, in which we observe an excited multimer state using ultrafast spectroscopy. Moreover, we show the precise engineering of DPP chromophore stacks, of which an exceptionally bright Pd2L2L’2 (>50% PLQY) benefits from an intra-assembly FRET process. Finally, the concept of chirality for light polarization control using supramolecular engineering will be explored.
