Making a chemical that changes color in different liquids

For this video, I decided to make Brooker’s Merocyanine, also called MOED, which exhibits solvatochromism. This means that it its color changes drastically, depending on the solvent that it’s dissolved in. I thought this effect was really cool and I wanted to try it out myself. Also, chemical companies sell it for hundreds of dollars a gram, and I wanted to see how much cheaper I could make it for.

You're sitting on a gold mine bro. Selling MOED and Red Mercury should make enough to keep this channel going for decades :P

“Ice Cold Ethanol” would make a great band name.

Now that you did it, you could upload your thumbnail to the Wikipedia. I'm sure a lot of people would be very pleased of see some HQ picture of this, with the solvents named with tags.

21:07 the moment he said "liquid rocket propellants" I sat up in bed from pure excitement. nilered, don't forget to take care of your glassware, too. we don't want something like the Great Plasma Shattering again...

"I still managed to make way more product than I needed, and I also learned something in the end, so this mistake really didn't bother me that much." This is why you are good at what you do.

Awesome video, NR! Strictly speaking, the two structures of MOED are resonance forms, not distinct equilibrating minima. Polar solvents cause a polarization of the electron density that makes the charged resonance form more representative of the true structure than the neutral form. As this occurs, the energy gap between the ground and excited states shrinks, causing a shift in color toward red.

Idea for edible chem: synthesize calcium sulfate and make tofu.

Have you tried making the Vanillin derivative? It should still be solvatochromic but produce different colors.

As a lifelong lover of chemistry, this is one of my favorite channels. At every step, I couldn't help but come up with explanations, rationales, or hypotheses for why things happened as they did. Keep up the good work!
