Thermal characterization of sexithiophenes regioselectively functionalized with electron donor methylsulfanyl groups

The Differential Scanning Calorimetry (DSC) profile of a homogeneous series of regioregular ?-methylsulfanyl sexithiophenes, with different substitution patterns and number of substituents, is reported. The DSC data show that the thermal characteristics of these compounds strongly depend on the regiochemistry of substitution.
