a

Polymerization conditions: T = 65 °C; working electrode = Pt mesh with area ≈ 6 cm2; counter electrode = Pt mesh separated from reaction mixture by methylcellulose gel saturated with (C2H5)4NBF4; reference electrode = Ag/AgI/0.1 M (n-C4H9)4NI;

b

Initiator concentration, [EBiB], was varied to target different degrees of polymerization (DP);

c

Other employed surfactants and copper ligands are listed in Scheme 2; tris(2-pyridylmethyl)amine (TPMA), 1-(4-methoxy-3,5-dimethylpyridin-2-yl)-N-((4-methoxy-3,5-dimethylpyridin-2-yl)methyl)-N-(pyridin-2-ylme-thyl)methanamine (TPMA*2), tris[2-(dimethylamino)ethyl]amine (Me6TREN), N,N-bis(2-pyri-dylmethyl)-2-hydroxyethylamine (BPMEA), and bis[2-(4-methoxy-3,5-dimethyl)pyridyl-methyl]octadecylamine (BPMODA*).
