CHEMILUMINESCENT MATERIALS
Abstract
Progress toward the development of chemiluminescent systems is reported with particular reference to systems encompassing the peroxy-oxalate- fluorescent compound mechanism. In a series of nine new oxalate esters, seven provided at least medium chemiluminescent intensities in standard qualitative chemiluminescence tests. The active compounds were all electronegatively-substituted aryl esters, thus confirming previous conclusions. Solubilities in several solvents were determined for the more promising compounds as a preliminary to quantitative examination. Bis(2,4dinitrophenyl) oxalate was investigated quantitatively in terms of reactant concentration effects and in terms of the effects of accelerators and inhibitors. Triethylamine and 2,4-dinitrophenol strongly accelerate the reaction; 2,6-di-t- butyl- 4-methylphenol has little effect on the reaction rate but severely reduces quantum yields. Fluorescer stability was found to increase at low hydrogen peroxide concentrations. In a series of eight compounds related to oxamide, four were found to be chemiluminescent in qualitative testing.
