Synthesis and optoelectronic properties of radical conjugated polyfluorenes

A novel redox-active fluorene monomer is synthesized and copolymerized with 9,9-dioctylfluorene and benzo[ c ][1,2,5]thiadiazole via Suzuki cross-coupling to produce alternating and tertiary copolymers. Electrochemical and chemical reduction of the copolymers generates organic polymeric radical anio...

Description
Summary:A novel redox-active fluorene monomer is synthesized and copolymerized with 9,9-dioctylfluorene and benzo[ c ][1,2,5]thiadiazole via Suzuki cross-coupling to produce alternating and tertiary copolymers. Electrochemical and chemical reduction of the copolymers generates organic polymeric radical anions. Electrochemical, spectroscopic, and photophysical characterization grant insight into the structure-property relationship for open-shell conjugated polymers. A novel redox-active fluorene monomer is synthesized and copolymerized with 9,9-dioctylfluorene and benzo[ c ][1,2,5]thiadiazole via Suzuki cross-coupling to produce alternating and tertiary copolymers.
