Polymers are often associated with plastic materials, generally known to be electrically insulating. Conjugated polymers (CPs), instead, are organic macromolecules consisting of a sequence of repeat units, where the periodic alternation of single and double bonds between carbon atoms allows for the formation of a continuum of energy states, delocalized along the backbones [1]. Because of this particular structure, the charge can flow across their length and they exhibit semiconductor properties, beside other advantages such as mechanical flexibility, robustness, lightness, low-cost and sustainable processability. All these properties are easily tuneable and make CPs promising candidates to be used in various applications in organic electronics and photovoltaics [2].
