dc.description.abstract | Molecular doping is essential for improving the thermoelectric properties of conjugated polymers, but dopants of low solubility either restrict the formation of high quality films or complicate fabrication steps. Although a highly soluble molecular dopant, tris(pentafluorophenyl)borane (BCF), has been sporadically studied, its potential has not yet been fully explored. Herein, particularly intriguing effects of Bronsted acid doping with BCF-water complexes for poly(3-hexylthiophene) (P3HT) are reported, which can facilitate substantial increases in electrical and thermoelectric properties with remarkable doping stabilities. Interestingly, a unique polymorph of P3HT with interdigitated alkyl chains (called type II) is observed in the Bronsted acid doping with BCF-water complexes. Moreover, the doped P3HT shows conformational change to the quinoid structure, enabling increased backbone planarity. As a result, the Bronsted acid-doped P3HT films exhibit outstanding electrical conductivities, thermoelectric power factors, and figure-of-merit of up to 33.0 S cm(-1), 28.3 mu W m(-1) K-2, and 0.034, respectively. These values are at least an order of magnitude higher than those of P3HT films doped with a conventional molecular dopant, 7,7,8,8-tetracyano-2,3,5,6-tetrafluoroquinodimethane. The Bronsted acid doping with BCF-water complexes also affords excellent air stabilities of P3HT films, which potentially provides a strong comparative advantage over existing highly reactive salt-type dopants, such as FeCl3. | en_US |
