Stimuli-responsive polymeric systems are of considerable interest due to their potential applications in environment-adaptive technologies such as smart surfaces. Traditionally, such systems can be constructed either by dynamic non-covalent or dynamic covalent chemistry, but the use of both chemistries in one system offers unique opportunities for structural diversity and various controllability. Herein, we report that hydrazone-pyridinum conjugates, which can be dynamically exchanged by transimination, can be assembled into one-dimensional wires by direct intermolecular interactions. The self-assembly process can be controlled not only by dynamic covalent chemistry, but also by pH adjustment. Such a dual control of the dynamic molecular assembly will provide a way to develop diverse smart materials with multi-stimuli-responsiveness. |
