제목 Molecular nanovalve based on mesoporous silica
초록 A nanovalve is constructed by combining a movable element that regulates the flows of gases or liquids with a reservoir which can also serve as a supporting platform for the movable element. A supramolecular nanovalve opens and closes the orifices around nanopores which accept and release small numbers of molecules such as luminescent probe molecules, drugs and enzymes. 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 MCM-41 and the mutual recognition between secondary dialkylammonium ions and DB24C8. In addition, we’ll show the operation of nanovalve by luminescence.
