We study the influence of the physical and chemical structure on the chiroptical response of fluorene-based polymeric systems, namely poly(9,9-dioctylfluorene) (PFO) and the

donor-acceptor type copolymer poly(9,9-dioctylfluorenealt-benzothiadiazole) (F8BT). We reveal the significance of magneto-electric coupling, at both short (molecular-level)

and intermediate (delocalised over multiple polymer chains) length scales, on the magnitude of the dissymmetry. These findings provide a framework for the design of new materials with an enhanced chiroptical response.
