    • note
    • The polydispersities of polymers 11, 12a, and 12b are all extremely high (i.e. >3), presumably due to heterogeneous conditions during the course of the polymerization reactions. In all cases, at least partial precipitation of the polymer from the reaction mixture was observed during the polymerization.

    • note
    • 1H NMR spectra of 12a and 12b did not provide significant insight into the regioregularity of these polymers. However, given that similar kinetics were observed for polymerization of either dialkoxy-diiodobenzene monomers or 5 with diethynylbenzenes, it seems likely that the polymers will be largely regiorandom.

    • Attempts to obtain polymer 12 in solvents such as THF or toluene led to smaller oligomeric materials, presumably due to the lower solubility of the coupled products in these solvents.
