    • We have checked by proton NMR that a broadened component, associated with ether molecules solvating the Grignard, is still present in the solution after solvent substitution. We have tried to eliminate the ether completely, either by thorough solvent substitution of by direct formation of the Grignard in benzene or dichlorobenzene. We have found that the Grignard precipitates when ether is completely removed from the solvent, and it is not formed in pure benzene or dichlorobenzene solvent. This is clearly a problem for reaching ultimate polymer purity

    • + elimination). However, our polymer layers can be quite thick and apparently exhibit a limited conjugation length, whence poor transport properties (they macroscopically appear rather insulating). In these conditions, it appears very unlikely that a charge-transfer reaction with the substrate could take place near the end of the chains
