Chemical doping of polymer-based organic semiconductors allows one to both increase the electrical conductivity, through increasing the charge-carrier density and/or filling charge-carrier traps, and reduce charge-carrier injection or extraction barriers. Though doping has been used since the earliest studies of conducting polymers, there remain open questions as to the chemistry of the doping process, the nature of the charge carriers (e.g., polarons), and the impacts of dopants on polymer structure and resulting materials properties that need to be addressed to develop more robust materials systems. Here we will discuss recent developments in understanding charge carriers and dopant–charge-carrier interactions in π-conjugated polymers, and how this information can be of use to design new dopant–polymer systems.
