Aqueous Peroxyoxalate Chemiluminescence

A quantum yield of 7.2% in aqueous solution has been obtained from the reaction of hydrogen peroxide with bis(N-2-(N'-methyl-2'-pyridinium)ethyl-N-trifluoromethylsulfonyl)oxamide in the presence of sulfonated rubrene as fluorescer. Light capacity of this system is 62 lumen hours per liter...

Description
Summary:A quantum yield of 7.2% in aqueous solution has been obtained from the reaction of hydrogen peroxide with bis(N-2-(N'-methyl-2'-pyridinium)ethyl-N-trifluoromethylsulfonyl)oxamide in the presence of sulfonated rubrene as fluorescer. Light capacity of this system is 62 lumen hours per liter of solution. A system using bis-hexylrubrene in an emulsified solvent gave a quantum yield of 8.3%. A record high quantum yield of 34% in an organic solvent was achieved with bis-(N-(2,4,5-trichlorophenyl)-N-trifluoromethanesulfonyl)oxamide, hydrogen peroxide and a fluorescer. (Author)
