We synthesized photosensitive luminol derivatives which had photoremovable protecting groups on the carbonyl oxygen of luminol to measure ultraviolet ray power. The photosensitive luminol derivatives released luminol by irradiation. The amount of released luminol increased with an increase in light power. Among the derivatives irradiated, photolysis of luminol-O-4′-methyl-7′-methoxycoumarin proceeded with a quantum yield of 0.035. The light power measurement with luminol-O-2-nitrobenzylate had a linear power range (0.8-6.5 J cm-2) and was applied to solar light power measurement.
