摘 要：Thermoresponsive polymers with simultaneous biodegradability and signal“self-reportingoutputs that meet for advanced applications are hard to *** address this issue,we developed fluorescence signal“self-reportingbiodegradable thermoresponsive polycarbonates through the immortal copolymerization of CO_(2)and oligoethylene glycol monomethyl ether-functionalized epoxides in the presence of hydroxyl-modified tetraphenylethylene(TPE-OH).TPE-OH was used as chain transfer agent to afford well-defined polycarbonates with controlled molecular weight(6000—17000 g·mol^(–1))and aggregation-induced emission *** temperature-dependent fluorescence intensity study,low critical solution transition of TPE-labeled polycarbonates were determined and the fine details of thermal-induced phase transition process were *** research indicated that temperature-controlled aggregation and dissociation of TPE moieties are the main reason for fluorescence intensity *** anticipate that this work could offer a method to visualize the thermal transition process of thermoresponsive polycarbonates and broaden their application fields as smart materials.
