Fig. 1. (a) Schematic illustration of reversing RAFT polymerization in the presence of Eosin Y under light irradiation. (b) Photothermal reactor set-up at different wavelengths. (c) Kinetics of light-accelerated depolymerization catalyzed by different concentrations of Eosin Y under green light. (d) Corresponding SEC traces of PMMA during depolymerization with 100 ppm Eosin Y. (e) 1H NMR spectra of the PMMA depolymerization, vinyl peak appearances over time confirming the monomer regeneration. Reactions were run in 1,4-dioxane at 5 mM and 100 °C in the presence of Eosin Y under green light.
