A valve is a machine constructed by combining a movable element that regulates the flow of gases or liquids with a reservoir which can also serve as a supporting platform for the movable element. Trapping and releasing molecules under deliberate control from nanoscale containers is an important challenge for applications in fluidics, sensors, and controlled drug release. Recently, researchers reported that a supramolecular system based on mesoporous silica MCM-41 as the supporting platform for movable elements and naphthalene-containing dialkylammonium ions / dibenzo[24]crown-8 (DB24C8) or 1,5-dioxynaphthalene containing derivative (DNPD) / cyclobis(paraquat-ρ-phenylene) (CBPQT4+) as the moving parts of nanovalves. In this work, we report constructing nanovalves based on mesoporous silica SBA-1 and SBA-3 and the mutual recognition between secondary dialkylammonium ions and DB24C8. |
