Fluorophores for Glow sticks
Before about one year I obtained bigger amounts of the fluorophores which are used in glow sticks.
I found a vendor in China, which offered my bulk amounts of following stuff:
100 g Perylene CAS:[198-55-0]
1000 g 9,10-BIS(4-ETHOXYPHENYL)-2-CHLOROANTHRACENE CAS:[135965-21-8]
1000 g 1,8-DICHLORO-9,10-BIS(PHENYLETHYNYL)ANTHRACENE CAS:[51749-83-8]
Here is a picture of the shipment:
The chemicals opened:
So I made a cocktail out of TCPO, Sodium salicylate, Mixture of ACN and Ethylacetate and 50% Hydrogen peroxide:
and let it glow (from top: Perylen, 9,10-BIS(4-ETHOXYPHENYL)-2-CHLOROANTHRACENE, 1,8-DICHLORO-9,10-BIS(PHENYLETHYNYL)ANTHRACENE)
I observed the weak glow of 9,10-BIS(4-ETHOXYPHENYL)-2-CHLOROANTHRACENE here:
So I changed the solvent to dimethyl phthalate:
and got a stronger glow:
Prices:
100 g Perylene for $450
1000 g 9,10-BIS(4-ETHOXYPHENYL)-2-CHLOROANTHRACENE for $1100
1000 g 1,8-DICHLORO-9,10-BIS(PHENYLETHYNYL)ANTHRACENE for $870
Delivery Fee (custom and tax included): 222.05 CHF
Now I have no problem if batch is wasted or I loose some dye at the balance....
At VWR you will pay for 25 g 9,10-Bis(4-ethoxyphenyl)-2-chloroanthracene $465.7.....
