Energy transfer-induced polymerization of acrylates

Photopolymerization of acrylate monomers has been the focus of research for quite a long time, but most of the researches concentrated on using exogenous radical species as means to achieve photo-induced polymerization. Herein, we exploit the energy transfer process between the luminescent molecule and the acrylate monomer to accomplish a two-component photoinduced polymerization reaction, and explored the universality of this strategy. Via the choice of thiochromanone as a template for the study, the photochemistry processes involved were explored in depth. The effect of radical polymerization processes was also excluded by time-resolved electron paramagnetic spectrum. As a result, it provides inspiration for further discussions on the roles played by monomers in photo-induced polymerization.
