Advances in electro-copolymerization of NIR emitting and electronically conducting block copolymers

Block copolymers comprising benzothiadiazole were successfully electro-copolymerized leading to (BTD-T2)n(BTD-F2)m, where n and m were varied in a perfectly controllable, well-defined manner. The polymers were characterized by cyclic voltammetry, AC-impedance, SEM–EDAX and XPS analyses. They exhibit absorbance and emission in the near infrared (NIR) region. Results support an efficient strategy towards the creation of even more complex materials with innumerable possible applications in optoelectronic.
