Phenols which markedly enhance chemiluminescence in the horseradish peroxidase catalysed oxidation of luminol by hydrogen peroxide show anomalously high reactivity (by factors of -102 compared with published Hammett correlations) in the reduction of the enzyme intermediates, Compound I and Compound

Systematic studies on phenol derivatives facilitates an explanation of the enhancement or inhibition of the luminol-H2O2-horseradish peroxidase system chemiluminescence. Factors that govern the enhancement are the one-electron reduction potentials of the phenoxy radicals (PhO./PhOH) vs. luminol radi
The chemiluminescence of the luminol-H 2 O 2 -horseradish peroxidase system is increased by fluorescein. Fluorescein produces an enhancement of the luminol chemiluminescence similar to that of phenolphthalein, by an energy transfer process from luminol to fluorescein. The maximum intesity and the to
