I just started perusing through some "light reading" on the molecular circuits, I'll post the links to a few papers that I found interesting. They're pretty interesting, so I hope you enjoy (if you choose to read them.)

Some parts of the article from the link above are useful. I don't think all of it is applicable to what we're looking to do, but it's good to see what's being done in the field at the moment.

Something I found by Professor Hess. It's interesting, and pretty understandable, just to get a grasp of what's going on.

I kindof understand what's going on in the paper above (thanks to orgo). But if we could work with some different chemicals with different bonding schemes (or maybe complementary is the right word), we could see how that could turn into something to investigate. I don't know if that's a bit too broad, though. This interestingly has to do with self assembly, something I worked with last summer. But I think self-assembly is something interesting to combine with the shuttles that we're thinking of.

That's it for now, I think this is enough to get a good grounding in the topic.

Happy Friday!

The molecular circuits thing seems really cool. However, I'm a little hesitant to approach it just because I'm having trouble thinking of a specific idea simple enough for us to do. The paper you linked had some impressively complex chemistry, and I'm just not sure if I have the background necessary to work on something like that.

The self-assembly thing seems a little more promising, given Ely's experience last semester and its closer relation to Professor Hess's work in the past. But again, I'm having trouble coming up with a specific idea on what we could do with it. I'll try to dwell on it some more.

In my mind there is a little distance between the molecular electronics field, where people use molecules (angstrom to a few nanometer size) to build electronic structures, and nanoscale electronics, where structures are dozens or hundreds of nanometers in size. The problem the molecular shuttles probably address best is not so much to build circuits from molecules, but rather the "wiring" part. Placing wires which are nanometers in diameter and micrometers long seems exactly the type of thing molecular shuttles could do.
