Abstract
Most organogel formation has been observed at low temperatures and the gel melts as the temperature increases. As an opposite case to traditional organogels, we report a reverse thermal gelation of methoxy-aminopoly(ethylene glycol)-homopolypeptide block-copolymer chloroform solutions that undergo a sol-to-gel transition as the temperature increases. A series of methoxy-aminopoly(ethylene glycol)-homopolypeptide block copolymers showing reverse thermal gelation in chloroform was synthesized and we prove that the secondary structure of the polypeptide determines the morphology of the organogel.
