Abstract

Control over the electronic structure in π-conjugated polymers is of great importance for the development of organic electronics and spintronics. In this study, we synthesized a sheathed cross-conjugated polythiophene through oxidative electrochemical polymerization. Spectroelectrochemistry has revealed that unlike linearly conjugated polythiophenes, polarons were confined in the repeating units that were segmented by cross-conjugation.
