Zartan? I don’t know any “Zartan!”

Probably the coolest application of photochromics =)

Photobleaching ruins the compound permanently, not just reverting it to clear, but making it incapable of greening again.

What would the internet be without scornful anonymous haters of anything? It’s literally been hours, HOURS, since the last equation I saw in JACS and that really isn’t fucking good enough.

I think the rapid photobleaching is one of the best things. Either you’re confused or I’m confused, but they make nothing out of the photostability of the compounds, or how quickly they degrade into inert side products. The rapid photobleaching is why it would make an excellent material for transition lenses and the like.

Uh-oh. You sound like a man scorned. Damn that JACS! Damn it to hell!

Sure! This could have been published in JACS or A.C.. Considering the kind of anecdotes they publish at the moment this fits more than well in those journals. Moreover, it contains no equations so its perfect for the kind of reader their editors are working for.

E pluribus unum. Triplet states aid international Islamo-fascism! Sigma-rho correlations, fuse some rings, add a transition metal in a resolved chiral environment… Why are grad students allowed to go home – or even wash – until the work is done? Chain them to their benches, epoxy on Texas catheters, have at it. Add a microsecond synchrotron radiation crystal structure at the end.

If it doesn’t have a photoisomerizable Ar-N=N-Ar or a rotaxane, how good can it be? And why not more nitrogens from Click chemistry? Reduce organic chemistry’s carbon footprint!

I almost posted that! Glad someone did. It’s cool.

So, I agree this could have done better than Org. Lett., but after reading through this a little more carefully, I see why they did.

There are still some unanswered questions they need to work out. For instance, why it worked in their NDPI system so much better than it did in their TPID system.

Also, I now see why they were flickering around the UV light so fast; not only to show how fast it works, but because the rapid photobleaching that takes place under continuous irradiation. That’s a problem that they’d need to work out, if it were going to be applied, say in the sunglass example you discussed.

Seems like a good idea just to get their idea out there somewhere, then when they go ahead and work that stuff out they can put it somewhere bigger.

Does derivation on video count?
