GISAXS patterns of pg2T-TT neat, ex situ electrolyte exposed, dedoped (-0.2 V vs Ag/AgCl), and redoped (+0.5 V vs Ag/AgCl) films were also collected (Figure ). Line-cuts from the neat and electrolyte exposed films were nominally identical (Figure ), implying no meso-scale disruption/reordering and a uniform distribution of passively incorporated ions. This stands in contrast to analogous alkyl sidechain polythiophenes exposed to ionic liquid electrolytes, where ions are presumed to preferentially enter the amorphous domains. Here, a uniform ion uptake in both amorphous and crystalline domains is in keeping with the large lamellar expansions in pg2T-TT upon electrolyte exposure seen with in situ GIWAXS. It is difficult to rationalize 60% lamellar expansion not reflecting significant ion uptake into the intra-lamellar regions of crystalline domains. Compared to the neat and exposed films, line-cuts from ex situ dedoped films displayed a subtle slope increase and intensity decrease, while line-cuts from ex situ redoped films displayed a subtle slope decrease and intensity increase. The relatively minimal scattering differences across conditions implies that passive ion uptake, and potential dependent (de)doping results in relatively uniform changes in ion density within the amorphous and crystalline domains of pg2T-TT in aqueous metal halide electrolytes.
