ABSTRACT
Smart polymers are special kinds of polymeric molecules that respond to external stimuli. We have developed a novel smart polymer designed to sequentially disassemble into its building blocks upon initiation by a triggering event at the polymer head. The polymer structure is based on a polyurethane backbone that disassembles through a domino-like, 1,6-elimination and decarboxylation reactions. We synthesized a self-immolative polymer that amplifies a single cleavage reaction into multiple release of fluorogenic molecules and confirmed the head-to-tail disassembly concept. These polymers can be used to prepare highly sensitive molecular sensors with large signal-to-noise ratios. The sensors should be useful for the detection of a wide range of biological and chemical activities through use of the appropriate trigger at the polymer head.
