Fig. 6. (A) Phase diagram of photo-PISA synthesized by ZnPcS₄⁻ mediated dispersion photopolymerization of HPMA. Polymerizations were conducted under the irradiation of 730 nm light (I = 60 mW cm⁻²) for 24 hours without prior deoxygenation in water at fixed reaction stoichiometries of [PEG₁₁₃-CDTPA] : [TEOA] : [ZnPcS₄⁻] 1 : 4 : 0.02. (B) TEM images of synthesized polymeric nanoparticles at 10 and 15 wt% solids content (note: TEM images at 20 wt% were presented in Fig. 5C).
