Conductivity polythiophenes

Some progress has also been achieved in the use of chiral polymer films at electrodes. Conductive polythiophenes containing optically active substituents in the 3-positions were prepared by electropolymerization of suitable monomers without apparent lc s of optical activity The polymer of exhibits distinct...

The most conductive polythiophenes have been prepared in anhydrous aprotic solvents of high dielectric constant and low nucleophilicity, such as acetonitrile [12,141], benzonitrile [146], nitrobenzene [147], and propylene carbonate [148,149]. Acetonitrile generally leads to powdery deposits or brittle films with conductivities typically between 0.02 and 10 S cm , whereas benzonitrile, nitrobenzene, and propylene carbonate give compact freestanding films with conductivities exceeding 100 S cm. ... 

The conductivities of the poly[C CPDT]s are particularly high (25-300 S cm" ), in line with most conductive polythiophenes. Poly[(C )2CPDT]s are on the...
