Abstract

Doping levels of conjugated polymers determine their conductivity, energetics, and optical properties. The recent discovery of highly conductive n-doped Poly (3,7-dihydrobenzo[1,2-b:4,5-b′]difuran-2,6-dione) (n-PBDF) has opened new possibilities for n-type conducting polymers in printed electronics and beyond. The ability to control its doping level holds interest for a wide variety of applications. Here we report a precise control over the doping levels of n-PBDF through chemical doping and dedoping. The dedoping reaction occurs through electron transfer and proton capture. Notably, the ionic dedopant, tris(4-bromophenyl)ammoniumyl hexachloroantimonate (Magic Blue), shows enhanced interaction with n-PBDF, leading to high dedoping efficiency. Furthermore, chemically dedoped PBDF can be redoped by various proton-coupled electron transfer agents. By tuning the n-PBDF thin films between highly doped and dedoped states, the system shows controllable conductivity in the range of five orders of magnitude, tunable optical properties, and energetics, thereby offering potential applications in various organic electronic devices.
