摘要: A new class of thermoresponsive dendronized polypeptides was prepared through highly efficient oxime ligation between oxyamino-substituted polylysines and aldehyde-cored oligoethylene glycol (OEG) dendrons. Their secondary structures behavior were investigated. Because the dendritic stable linkage, these OEG-based exhibited fast fully reversible phase transitions in neutrally aqueous solutions, their transition temperatures can be controlled around physiological temperatures. The effect OEG dendronization on examined to check prominent shielding effect, steric hindrance, thermally driven transitions. To further extend functions potential applications stimuli-responsive polypeptides, phenylboronic acid moieties introduced achieve corresponding copolymers, which utilized specifically recognize c...
