Pentacene.

That's so cool! It looks like a bunch of fuzzy caterpillars.

I was wondering if they were using tunneling electron microscopy for the image, but it seems I'm about a generation behind: it's an Atomic Force Microscope.

Wow!

Its interesting because that technology is "primitive" in it's form, yet incredibly advanced. Unfortunately we aren't able to do this for molecules that have "volume", like proteins and such.

One interesting feature to note about the picture is that the carbon-carbon bonds are all the same size (length).

The wikipedia article I quoted uses the old notation for a benzene ring, depicting alternating single and double carbon-carbon bonds. The newer notation for a benzene ring - a hexagon with a circle inside it - arose when chemists or physicists discovered that the bonds in a benzene molecule are all the same length: about half-way between the length of a single carbon-carbon bond and a double carbon-carbon bond.

didn't know we had some fellow chemistry nerds here on s2ki

Isn't this because the electrons are constantly being shuffled around the ring?
