Abstract
Bergman cyclization of hyperbranched enediynes for generating spatially locked persistent radicals. HBPs with embedded enediyne moieties and many iodine groups in the peripheral are synthesized through one-pot Sonogashira cross coupling reaction of AB2-type monomers and functionalized by modification with phenylacetylene to get a series of fluorescent HBPs (HBEPs). The HBEPs are further subjected to thermal Bergman cyclization, producing polymeric networks with abundant free radicals locked inside, which are stable for a long time at room temperature, and can be slowly quenched when exposed to air.134
