Ha, I should have known! I was imagining a kind of triangular version of graphene, and thinking "That'll never work". You could put Oxygen or Sulphur or something in there instead of the Hydrogen, and possibly get a sheet with a bumpy surface. Not that there's much point, as we have graphene.
Maybe (if Adrian's idea of a neutron-rich surface being good for catching neutrinos is anywhere near the mark) an aligned double layer of graphene with a neutron-dense atom caught between each pair of hexagons might be of some use. Pile a few hundred such sheets together, and you might get a fairly neutron-dense surface. It would still look like empty space to a neutrino, though.
I'm talking rubbish, aren't I? Plain old lead would be much better. Oh, well..
Love those 'platonic hydrocarbons', though. Cool!
