WebJun 15, 2015 · Self-immolative linear polymers are a recently developed class of materials that typically undergo head-to-tail depolymerization in response to the cleavage of stimuli-responsive end-caps from their termini. These polymers have been inspired by self-immolative dendrimers and oligomers that undergo cascades of cyclization and/or … WebDec 13, 2024 · Self-immolative polymers are an emerging class of macromolecules with distinct disassembly profiles that set them apart from other general degradable materials. These polymers are programmed to disassemble spontaneously from head to tail, through a domino-like fragmentation, upon response to extremal stimuli.
WebSelf-Immolative RAFT–Polymer Protein Conjugation By applying excess symmetrical nitrophenyl carbonate disulfides to the RAFT end groups, protein-reactive end groups can … WebTo demonstrate the concept, 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 ...
WebSelf-immolative elimination occurs when a molecular system undergoes a spontaneous and irreversible disassembly into its constituent fragments through either an electronic cascade, viaan elimination pathway or, alternatively, where self-immolation is achieved through a cyclisation–elimination event. WebJun 15, 2024 · Some researchers have turned to the field of self-destructive, or so-called self-immolative, polymers to develop new thermoplastics. Pioneered by chemist Doron Shabat of Tel Aviv University, self-immolative polymers are inherently unstable but have an endcap that prevents their depolymerization.
