A novel strategy was developed to introduce a luminophore into generic polymers through mechanical stimulation, resulting in the successful incorporation of a luminophore into the polymer. This method allowed for the direct preparation of luminescent polymeric materials, potentially transforming existing commodity polymers into more valuable functional materials.
Herein, we report a novel strategy for introducing a luminophore into generic polymers facilitated by mechanical stimulation. In this study, polymeric mechanoradicals were formed in situ under ball-milling conditions to undergo radical-radical coupling with a prefluorescent nitroxide-based reagent in order to incorporate a luminophore into the polymer main chains via a covalent bond. This method allowed the direct and conceptually simple preparation of luminescent polymeric materials from a wide range of generic polymers such as polystyrene, polymethyl methacrylate, and polyethylene. These results indicate that the present mechanoradical coupling strategy may help to transform existing commodity polymers into more valuable functional materials.
