A UV‐Blocking Polymer Shell Prevents One‐Photon Photoreactions while Allowing Multi‐Photon Processes in Encapsulated Upconverting Nanoparticles

: Unintentional photorelease triggered by UV light is a problem in photodynamic therapy. Encapsulating upconverting nanoparticles containing photoswitches in a UV‐blocking amphiphilic polymer shuts down the one‐photon process and only allows two‐photon‐driven photochemistry. Thus, UV light is blocke... Full description
