Facile and green fabrication of organic single-crystal hollow microanostructures

摘要

Under high humidity and appropriate temperature, tris (8-hydroxyquinoline) aluminum (Alq3) solid microanostructures may be etched into hollow structures and still retain their crystalline structures and surface morphologies. The shapes and sizes of the hollow structures are easily adjusted by varying the experimental parameters. Throughout the entire process, water is introduced into the system instead of organic or corrosive solvents, making this method convenient and environmentally friendly; it can also be extended to application in other materials such as TCNQ.
