TL;DR: In this article, the properties of molecularly doped films of conjugated polymers are explored as the crystallinity of the polymer is systematically varied using Solution Sequential Processing (SqP) to introduce 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ) into poly(3-hexylthiophene-2,5-diyl) (P3HT).

Overcoming Film Quality Issues for Conjugated Polymers Doped with F4TCNQ by Solution Sequential Processing: Hall Effect, Structural, and Optical Measurements

TL;DR: It is demonstrated that solution-sequential processing (SqP) can yield heavily doped pristine-quality films when used to infiltrate the molecular dopant 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ) into pure poly(3-hexylthiophene) (P3HT) polymer layers.

Designing Conjugated Polymers for Molecular Doping: The Roles of Crystallinity, Swelling, and Conductivity in Sequentially-Doped Selenophene-Based Copolymers
D. Tyler Scholes,Patrick Y. Yee,George R. McKeown,Sheng Li,Hyeyeon Kang,Jeffrey Lindemuth,Xun Xia,Sophia C. King,Dwight S. Seferos,Sarah H. Tolbert,Benjamin J. Schwartz +10 more
TL;DR: Although chemical doping is widely used to tune the optical and electrical properties of semiconducting polymers, it is not clear how the degree of doping affects the electrical properties as mentioned in this paper.
Journal ArticleDOI
Dopant-Induced Ordering of Amorphous Regions in Regiorandom P3HT
TL;DR: 2-D grazing incidence wide-angle X-ray scattering is used to demonstrate that adding oxidizing small-molecule dopants into the amorphous conjugated polymer, regiorandom poly-(3-hexylthiophene-2,5-diyl) (RRa-P3HT), improves polymer ordering and induces a change in domain orientation from isotropic to mostly edge-on.
Journal ArticleDOI
Evaporation vs Solution Sequential Doping of ConjugatedPolymers: F 4 TCNQ Doping of Micrometer-Thick P3HT Filmsfor Thermoelectrics
Matthew T. Fontana,Dane A. Stanfield,D. Tyler Scholes,K. J. Winchell,Sarah H. Tolbert,Benjamin J. Schwartz +5 more
TL;DR: For thermoelectric and other device applications, there has been great interest in the chemical doping of conjugated polymer films as mentioned in this paper, and solution doping followed by film deposition generally produces poo
