Abstract : Results from a program designed to optimize the operating characteristics of peroxyoxalate chemiluminescent systems are reported. In particular, the effects of oxalate ester structure, fluorescer structure and certain reaction variables on the light capacities and emission lifetimes of such systems are described. A survey of the effects of a large number of additive components on the lifetimes and efficiencies of several oxalate ester chemiluminescent systems provided additives effective for both lifetime control and light capacity improvement. High light capacity systems are now available with lifetimes variable between one minute and 2 1/2 hours. Investigations of reaction products, reaction intermediates, oxalate ester preparation and oxalate ester stability are reported. The structure of a previously reported efficient chemiluminescent material was identified as bis(1-(1H)-2-pyridonyl) glyoxal. Efficient peroxyoxalate chemiluminescence has thus been extended from the ester to the amide series. (Author)
