Vice versa donor acceptor fluorene-ferrocene alternate copolymer: a twisted ribbon for electrical switching

Two donor-acceptor type copolymers (PFFC-1 and PFFC-2) containing ferrocene and fluorene moieties have been successfully synthesized to evaluate the redox triggered optical and electronic properties. Interestingly, PFFC-1 shows a twisted ribbon-like morphology at the liquid interface and switches to a micellar structure on oxidation.
