We found that melamine in its protonated form could be triggered by oxoanions such as NO3-, PO43-, ATP, and SO42- to form superstructures and to gelate a large amount of water molecules, presumably resulting from the electrostatic and hydrogen bonding interactions operating in a synergistic manner; the gelation can be reversibly switched off/on by increasing/decreasing pH or temperature.
