Reactions of 9-Phosphorylacridines with Aqueous Hydrogen Peroxide Accompanied by Weak Chemilumine-scence: Remarkable Substituent Effect on Emission Efficiency
摘要:
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.

A visible chemiluminescence (CL) has been found from the air oxidation of 9-benzyl-10-methylacridinium iodide, in contrast to the case of 9-benzylacridine, from which only a feeble CL could be detected. The difference in the CL quantum yields from the acridinium salt and acridine is interpreted in terms of a “CL quenching” of the chemiexcited species by benzaldehyde generated simultaneously in a solvent cage.
