Heterogeneous Photocatalysts for Light‐Mediated Reversible Deactivation Radical Polymerization

Heterogeneous photocatalysis combines the benefits of light-mediated chemistry with that of a catalytic platform that facilitates re-use of (often expensive) photocatalysts. This provides significant opportunities towards more economical, sustainable, safe, and user-friendly chemical syntheses of both small and macromolecular compounds. This contribution outlines recent developments in the design of heterogenous photocatalysts and their use to mediate polymerizations. We outline four classes of heterogeneous photocatalysts in detail: nanoparticles, conjugated and non-conjugated polymer networks, metal-organic frameworks (MOFs), and functionalized solid supports.
