Abstract

Certain phenalenone and benzphenalenone fluorescent compounds are useful in biomedical studies and analytical determinations. These compounds are particularly useful in assays for living organisms, e.g. microorganisms, carried out at a pH of 9 or less. For these determinations, the compounds can be attached to reducible compounds which will subsequently release the fluorescent moiety upon reduction. In the presence of an electron transfer agent, the reducible compounds are easily reduced by a microorganism.
