A fabrication report with mobility measurements of 0.12 cm2/Vs for M104 can be found below.
All the P3HT below is highly soluble (50 mg/ml) in chlorinated solvents such as chloroform, chlorobenzene, dichlorobenzene and trichlorobenzene. The intermediate and lower molecular weight P3HT materials are recommended for use with non-chlorinated solvents such as xylene, toluene and THF due to their increased solubility.
