We report a series of nanocage-composites tailored with coordination network, which can exhibit mechanochemically and electrochemically responsive release characteristics for guest payloads. The guest molecules are entrapped into the porous channels of mesoporous silica nanoparticles (MSNs), and the exterior was simply wrapped with coordination network to stabilize entrapped guests. The resulting nanocomposite exhibited guest release characteristics by dissociation of the coordination complexes induced by ultrasound. Integration of the nanocapsules with polymer matrixes enabled a series of responsive composites capable of successive guest release from the channels of MSNs upon repeated ultrasounds, compressions, or electrical input.
