논문초록 Organic conductors have recently drawn significant attention due to their potential applications in optoelectronic devices. The use of molecular doping to achieve an electrical conductivity of >100 S·cm−1 through efficient charge carrier generation has been restricted to conjugated polymers (CPs) composed only of thiophene or its derivatives. In this contribution, a novel conjugated CP, containing both electron donating isoindoloindole (IDID) and thiophene moieties, was designed for a molecular doping platform and characterized primitive doping characteristics through molecular sequential doping. To maximize doping efficiency, new doping approaches, such as sequential cascade doping and hybrid doping, were devised, and both provided outstanding electrical conductivity, over 600 S·cm−1. The properties of doped CP film, such as carrier densities, mobility, and conductivity, were directly quantified using Hall effect device, and its thermoelectric performance was characterized.
