Impact of Sequential Chemical Doping on the Thin Film Mechanical Properties of Conjugated Polymers.

ABSTRACT: Conjugated polymer (CP) films with nanometer-scale thickness exhibit unique properties distinct from their bulk counterparts, which is an important consideration for their end application as thin film devices. In the realm of organic electronic devices, enabling high electrical conductance properties of CPs often necessitates doping. However, the impact of doping on intrinsic polymer mechanical properties, such as the elastic modulus, in ultrathin films at device-relevant thicknesses is not well understood and has not been directly measured. In this study, we quantified the effect of doping on the mechanical properties of poly(3-alkylthiophenes) (P3ATs) using pseudofree-standing tensile testing. We observed modulation of the mechanical properties of ultrathin CP films through sequential do
