Fluorescence Thermochromism | CuI & Pyridine

Cool

Cool

Add a bit of acetone and potassium iodide and it's fluorescent at room temp.

Try not to get copper iodide on anything it can be hard to remove.

Pyridine if unavailable can be distilled from copper carbonate and niacin, and it stinks.

That was cool in all senses. 👍🏻

🤩 wow

Does that come from the pyridine? (Is CuI florescent in different solvent, like glass for instance)
Is the frequency shifted because of quantum state like LED's or does the complex change conformation at lowered temperature?
I wonder what spectroscopy would tell us, if I had any idea how to read a spectrograph......

Awesome 👍👍👍

Does the dry ice work instead of liquid nitrogen!?

It's my first shorts on YT! Hope you'll enjoy it! :^)
