Thermochromic derivatives of crystal violet


While looking for some interesting dyes I could synthesize with the materials I have and found a note on thermochromic derivatives of crystal violet. It may be of interest to others.

I don't know who invented mRNA vaccines but they should get a fancy medal and I hope they made a shed load of money from it.

I wounder if sulfonepthaleins are thermochromic.

Here is a synthesis of phenolsulfonephthalein (and some related dyes) it uses saccharine that is very OTC.
