Chyros' chemistry thread

On another note: a friend of mine works in physical organic chemistry making organic substrates and has lots of colourful compounds, such as this one. Here you can see a beaker of one of his samples under a blacklight.
Explain what is happening here.

so the colorful glowing ring/tube toys, that usually found at night carnivals or concerts, are not fluorescent? o:

@ n5p29: eh, it's time for some more formal terminology to explain this. It's neither fluoro- nor phosphorescent - it's chemiluminescent since the light comes from a chemical reaction between H2O2 and Ph2(COO)2. Fluoro- and phosphorescence emit light because they absorb light, not because of a reaction.

The molecules absorb energy in the form of UV light, which brings them into a higher-energy state. This higher-energy state relaxes back into the "normal" state with loss of energy, namely the light emitted from the molecule. Kinda like this (except not a laser but UV)

In retrospect I found I had kept it a bit short .
Also, the reason why the organic molecule was fluorescent was because it has a highly conjugated system (many alternating double bonds) which allow it to take up and delocalise electrons easily. This excess energy is then emitted again in the form of visible light.

If I made some kind of massive cockup I would just re-record the movie, though .

I'll have to think of some other way, I guess.

After a rather long pause here I'm gonna throw in a fun picture of a reaction done using a very powerful UV lamp. The lamp is so powerful that you need serious tinfoil to keep the light in otherwise everybody who gets near loses eyesight pretty immediately. The lamp also has to be cooled constantly because otherwise it would melt itself.
I have some more stuff in the pipe that I want to show, but first I need a video to explain the principles of it and I've tried four or five takes now which have all failed. I'm trying to get it on ASAP without too many messups in it .

Now if i could only incorporate that into a computer case...
