The reaction of 9-phosphorylacridines with aqueous hydrogen peroxide provides weak chemiluminescence, whose emission efficiency depends on the structures of the phosphorus groups. The bulky substituents in the phosphorus groups increased the chemiluminescence quantum yields, which can be explained by assuming that the present chemiluminescence reaction involves a CIEEL process via phospha-1,2-dioxetanes as the high-energy intermediates.
