  "abstract": "Recyclable polymeric materials capable of generating radicals under mild conditions are valuable materials in synthetic chemistry. Herein, we report polystyrene‐based copolymers bearing 2,2′‐(pyridine‐2,6‐diyl)diphenol (PDP) moieties that form alkyl borate complexes and release alkyl radicals upon blue‐light irradiation. The generated primary and secondary alkyl radicals efficiently participate in Giese‐type addition reactions, affording products in good to excellent yields. The polymer‐supported system enables straightforward purification by simple reprecipitation at both the borate complex formation and Giese reaction stages. Notably, the PDP polymer can be recovered through fluoride‐mediated cleavage and regenerated via recomplexation, allowing reuse in subsequent reaction cycles. In addition, crosslinked PDP–borate networks function as photodegradable organogels that selectively absorb organic solvents from water and release them upon light irradiation. This polymer‐supported strategy provides a versatile platform for photo‐driven radical transformations and responsive materials applications, demonstrating proof‐of‐concept for polymer recovery (50% PDP regeneration) and practical advantages in product separation.",
