Abstract

A self-reporting, profluorescent, visible light-induced release system is introduced. Fluorescence activation is enabled by a mild remote trigger signal that can be monitored with the naked-eye in real time. The light-responsive spin-silenced polymer is synthesized via an Ugi post-polymerization modification incorporating paramagnetic nitroxides and a light cleavable fluorophore moiety.

Keywords: Ugi reactions; fluorescence; nitroxide chemistry; sensors; visible light photochemistry.
