Photoactive Nanowires in Fullerene-Ferrocene Dyad Polyelectrolyte Multilayers

Layer-by-layer (LBL) films of a fulleropyrrolidinium-androstane-ferrocene dyad revealed a surprisingly high level of intermolecular organization. In particular, in every adsorption layer, the films self-assemble into linear nanowire superstructures. Given the inherent intramolecular charge transfer performance of the dyads, such a film organization facilitates the charge diffusion from the photoactive centers to the electrodes, due to extensive interpenetration of the layers, which leads to multiple contacts between the fullerene-ferrocene nanowires.
