Abstract

Peroxyoxalate chemiluminescence (PO-CL) was investigated using eight oxalates with various phenol moieties and the distyrylbenzene (DSB) fluorophores with various substituents. The ρ-values in the Hammett correlation between the substituent constants (σp+) of the DSBs and the singlet chemiexcitation yields (ΦS) for the PO-CL reactions varied from− 0.50 to− 1.01 depending on the oxalate structure, and the reactive oxalates tended ...
