    • Based on the generally accepted mechanism for Stille coupling reactions, we anticipate that at least 5-10% homocoupling of the thienyl-stannane derivative will occur during the polymerization. The occurrence of thienyl-stannane homocoupling will result in the insertion of one extra thiophene ring between the dendritic substituents. In light of the relatively low extent of homocoupling and the minimal degree of substitution along the polythiophene backbone, we do not expect this to significantly affect the overall polymer structure, especially for polymers derived from the pentathiophene macromonomers. For a more detailed discussion on the effects of homocoupling, see ref 13a.

    • It is interesting to note that PG2T5 does not precipitate out of solution during the polymerization, but rather gels and takes the shape of the flask during the reaction, thus forming a malleable, continuous material having a lustrous greenish-red metallic appearance. We do not believe that this is due to cross-linking but rather due to the unique properties imparted by the aliphatic ether dendrimers.
