Random Copolymers of Alkyl Thiophenes

Random copolymers of 3-octylthiophene and 3-methylthiophene were prepared electrochemically and upon doping these copolymers were more thermally stable than the homopolymers [104].

The solution UV-Vis data for the copolymers 31-33 indicated that increasing the amount of dodecyl side chains increases the solution disorder leading to a non-planar structure [105]. However, in the solid state, the polymers with a higher percentage of dodecyl side chains self-assembled in order to form planar structures with 

Conductivity results indicate that I2 doped thin films (0.5-4 m) of polymers 31 and 33 exhibited electrical conductivities in the range of 50-200 S cm [76]. In addition, the physical properties of these polymers were unchanged over molecular weights of number average molecular weights (M ) ranging from 9-28K (PDI = 1.6). Therefore, apparently the physical properties appeared not to be a function of the molecular weight.
