Abstract
The sustainable application of chemiluminescence technology benefits from the development of efficient chemiluminescent reactions in water. The peroxyoxalate reaction is used in self-illuminating devices, such as light sticks, and has high emission quantum yields in organic solvents. Here, we demonstrate that by encapsulating bis(2,4,6-trichlorophenyl) oxalate and the dye rubrene within microspheres of cellulose carboxylic esters, the chemiluminescence quantum efficiency of the peroxyoxalate reaction in water can be enhanced by two orders of magnitude. These findings indicate that the encapsulation of reagents of the peroxyoxalate system holds promise for its advantageous application in analytical and bioanalytical assays conducted in aqueous media.
