Dicationic Ion-Pair Doping Enables Stable and High-Performing Conducting Polymers for Organic Thermoelectrics. [PDF]

Adv Sci (Weinh)
TAB–2TFSI enables efficient ion‐pair doping across a wide range of conjugated polymers, where the strongly oxidizing TAB core drives charge transfer, and the TFSI counterions promote favorable ionic compensation. This dicationic dopant promotes uniform dopant distribution, improves structural order, and increases carrier delocalization, establishing a ...
