First, at low 𝑞 (𝑞 < 0.02 Å -1 ) a power law of ~-1.2 to -1.6 is observed instead of an overall Guinier region preceded by constant flat intensity indicating that the PII-2T chains are not dispersed but are aggregating into a larger structure. Such low 𝑞 power law scattering and even steeper is commonly observed in small angle scattering of conjugated polymers . Given the known tendency of PII-2T to form nanofibrils 31 a slope of -1.2 to -1.6 at this length scale is expected, corresponding to a large semiflexible object in between that of a rigid rod (-1) and random coil (-2). We note that this low 𝑞 slope does vary slightly from experiment to experiment in the range of -1.2 to -1.6 indicating the exact aggregation structure is highly sensitive to the solution preparation conditions but still exhibits a semiflexible nature in all cases.
