[a]
Conditions are [1000]:[×]:[1]:[30] of [monomer]:[DBMM]:[PC 2]:[LiBr] with 1.5 mL DMAc relative to 1 mL monomer performed in continuous-flow and irradiated by 18 W 365 nm LED at 22 ºC.
[b]
Reaction components sparged with air for 30 minutes before polymerization. See SI for full experimental details.
