We were trying to develop a new synthetic methodology for semiconducting organic polymeric model compounds. The main objective behind this work is to understand their conduction mechanism, their efficiency compared to existing organic polymers.
Initially you can measure impedence of the SOC. However, it is better to make a thin film to observe its conductivity directly or you can construct an working electrode using SOC to measure the current as well as conductivity. You can see the articles:

conductivity measurement itself will not explain "conduction mechanism"; for this topic, you need to combine several methods, like
- morphology (SEM, TEM, AFM) and structure (XRD) studies (which needs to be extremely well resolved!)
- conductivity vs temperature down to very low temperature
- AC vs DC
You can find several related papers in my RG pages.
In a recent communication, ( Liu, et al., Materials Horizons 4, no. 4 (2017): 608-618), a unified picture of charge transport in organic semiconductors is discussed. You may refer to it and references therein. There is thorough information about different procedures of conductivity measurement and mechanisms involved.
