^aReactions conditions: [OEOMA₅₀₀]/[HOBiB]/[EYH₂]/[CuBr₂]/[TPMA] = 200/1/x/x/x, [OEOMA₅₀₀] = 300 mM, in PBS with DMSO (10% v/v), irradiated for 30 min under green LEDs (520 nm, 9.0 mW cm⁻²) in an open vial with stirring at 0–1000 rpm.

^bRevolutions per minute (rpm).

^cMonomer conversion was determined by using ¹H NMR spectroscopy.

^dMolecular weight (M_n,abs) was determined by Mark–Houwink calibration.

^eApparent molecular weight (M_n,app) and dispersity (Đ) were determined by GPC analysis (DMF as eluent) calibrated to poly(methyl methacrylate) standards.
