Multi-stimuli responsive novel polyimide smart materials bearing triarylamine and naphthalimide groups

摘要： Multiple stimuli-responsive smart polymers have received increasingly attention in recent years. In this work, a series of novel polyimides (PIs) bearing triarylamine and naphthalimide perssad were devised and prepared. These novel polyimides are able to respond to four different stimuli (light, pH, explosives and voltage) and perform four functions (light detectors, electrochromism, fluorescence detectors and memory devices). Furthermore, the smart materials are suitable for complicated environment. This work will open a new route for the development of novel smart materials with multi-functional and multiple stimuli-responsive properties.
