| After more than two decades, conjugated polymers (CP) continue to receive much attention due to their promise as low-cost active components in consumer electronics including LEDs, RFID tags, thin-film transistors, sensors, and photovoltaic (solar cell) applications. While CP synthesis is dominated by transition-metal catalyzed reactions, we employ nucleophilc activation of silicon-carbon bonds by catalytic fluoride sources, for the transition-metal-free, synthesis of a series of alternating copolymers containing thiophene moieties and perfluorobenzene. We also report that the electronic and optical properties of these copolymers can be manipulated by varying the substituents and backbones and controlling self-assembly of the polymer chains in the solid state. |
