TCPO, or bis-2,4,6-(trichlorophenyl)oxalate, is the main chemical in glow sticks.
Uses
TCPO is one of the major ingredients in glow sticks. When combined with 9,10-bis(phenylethynyl)anthracene, a solvent (such as diethyl phthalate), and a weak base (usually sodium acetate or sodium salicylate), and hydrogen peroxide, the mixture will start to weakly glow an aqua-green color[1].
Red, yellow and blue colours can be made by replacing the 9,10-bis(phenylethynyl)anthracene with Rhodamine B, Rubrene and 9,10-diphenylanthracene respectively.
In a glowstick a fluorescent dye converts much of the light energy produced into the visible spectrum producing a brighter glow.
Preparation
TCPO can be prepared from a solution of 2,4,6-trichlorophenol in a solution of dry toluene by reaction with oxalyl chloride in the presence of a base such as triethylamine. This method produces crude TCPO with a by-product of triethylamine hydrochloride.
