    • The polymerization was intentionally stopped prior to 100% monomer conversion in order to achieve the optimum level of molecular weight control and accounts for the depressed yield.

    • note
    • Given the multistep nature of the bpy-centered diblock syntheses and the tendency of certain ATRP reactions to become less controlled at high monomer conversions as evidenced by higher PDIs, excess monomer was utilized and polymerization was intentionally stopped prior to completion. High monomer loadings also enhanced macroinitiator solubility, in certain cases.
