Graphyne is interesting because these double and triple bonds create holes between the carbon atoms that are large enough for water molecules to pass through. However, these holes are not big enough for sodium and chloride ions, which are larger because they attract a shell of water molecules since they are charged.

Water passes through graphyne at a rate some two orders of magnitude faster than through the polymer membranes used in conventional reverse osmosis techniques. They are in the lab stage for production of graphyne.
