A nanovalve is an assembly of two or more molecular components designed to perform mechanical-like motions in response to stimuli, which include chemical, electrochemical, and photochemical pulses, that can be switched in and off at will. Recently, researchers reported that a supramolecular system based on mesoporous silica MCM-41 as the solid support for the molecular machinery comprising the movable elements and naphthalene-containing derivative / cyclobis(paraquat-ρ-phenylene) as the moving parts of nanovalves. In this work, we report the operation of nanovalve based on mesoporous silica SBA-15 as well as MCM-41 as the supporting platform for the movable elements, and the containers in which guest molecules are trapped and then released on demand. In addition, we used alkylsilane-containing secondary dialkylammonium ions and sufficiently large macrocyclic materials as the moving parts of nanovalves and anti-inflammatory drug as the guest molecules. |
