General description
Lumichrome (7,8-Dimethylalloxazine) is a natural metabolite of riboflavin. It is a flourescent photoproduct of riboflavin degradation. It is known to be an effective photosensitizer and a fluorescent dye.
Application
Lumichrome is suitable as a fluorescence probe, metal ion sensor, and may be used for the inactivation of biological contaminants. Its applications are also seen in memory and semiconductor devices.

Lumichrome photophysical properties at different pH were characterized by UV-vis spectroscopy and steady-state and time-resolved fluorescence techniques, in four forms of protonation/deprotonation: neutral form, two monoanions, and dianion. The excited-state lifetimes of these forms of lumichrome were measured and discussed.
